Regina’s Question: Is This Manipulation, or Something Else?

Regina is 49, a hospital administrator, the kind of person whose calendar is color-coded by department. She sits down across from me on a Tuesday in late March, still in her lanyard, a half-finished protein bar wrapped in foil on the arm of the chair. “I need you to tell me if I’m being manipulated,” she says. “I need an actual answer. Not a maybe.”

Her husband had cried in the car that morning, she tells me, a full collapse over a comment she’d made about being late to his sister’s birthday dinner. By the time they arrived, he was laughing, telling the valet a joke, his hand warm on her back like nothing had happened. “I felt insane,” she says. “I felt like I’d hallucinated the whole thing.”

Here is what I don’t do in that moment, and what I want to be direct about before we go any further: I don’t diagnose her husband. I’ve never met him. No responsible clinician diagnoses a person who isn’t in the room, isn’t being assessed, and hasn’t consented to that conversation. What I can do with Regina is something narrower and, I think, more useful. I can help her understand a pattern that shows up often in relationships where one partner has traits consistent with Histrionic Personality Disorder, whether or not that’s what’s happening in her specific marriage. This is a different starting point than the one I use with clients untangling covert narcissistic patterns, where the emotional mechanism runs in a different direction entirely.

What I see consistently in my practice is that clients arrive wanting a verdict: is this manipulation, yes or no. The honest clinical answer is almost always more complicated than that binary allows. Some behaviors that look manipulative from the outside function, for the person doing them, as something closer to a fire alarm going off in a nervous system that never learned how to regulate itself any other way. That doesn’t make the behavior harmless. It changes what kind of problem it is.

Regina sat with that for a long moment. “So it’s not manipulation,” she said, testing it. “It’s manipulation,” I told her, “but the question underneath your question is whether it’s intentional. And that’s a different thing to ask, and a different thing to plan around.”

What HPD Actually Is, According to the DSM-5-TR

Histrionic Personality Disorder is a diagnosis, not a personality description you can apply to someone dramatic at a dinner party. According to the DSM-5-TR (American Psychiatric Association, 2022), HPD is defined by a pervasive pattern of excessive emotionality and attention-seeking beginning by early adulthood, present in a variety of contexts, with at least five of eight specific criteria: discomfort when not the center of attention, inappropriately sexually seductive or provocative interactions, rapidly shifting and shallow emotional expression, consistent use of physical appearance to draw attention, impressionistic speech lacking detail, self-dramatization and theatricality, high suggestibility, and a tendency to see relationships as more intimate than they actually are.

Notice what’s absent from that list. Manipulation is not a diagnostic criterion for HPD. Intent to deceive is not a diagnostic criterion for HPD. The DSM-5-TR describes emotionality and attention-seeking, full stop. What partners experience as manipulation, guilt trips, sudden crises, shifting stories, often grows out of those eight traits colliding with a relationship, but the diagnosis itself says nothing about whether the person means to control anyone.

This is worth sitting with, because most of what circulates online about HPD collapses the disorder and the behavior into one thing: “HPD is manipulation.” It isn’t. Treating a diagnosis and a behavior as synonyms flattens a much more specific clinical picture, and it makes it harder, not easier, for partners to figure out what they’re actually dealing with. I see a similar flattening happen around HPD and BPD, two presentations that share surface features but very different underlying mechanisms.

Intentional Manipulation Versus Emotional Dysregulation: Why the Difference Matters

Here is the clinical distinction I spend the most time on with clients like Regina. Manipulation, in the everyday sense partners mean when they use the word, usually implies a goal: someone wants a specific outcome and deploys a tactic, consciously or semi-consciously, to get it. Emotional dysregulation is different. It describes a nervous system that has difficulty modulating the intensity, duration, or expression of feeling, so that the reaction often outpaces, and sometimes obscures, whatever triggered it.

Drew Westen, PhD, professor of psychology and psychiatry at Emory University, has spent much of his career studying the ways unconscious processes shape behavior in personality disorders. What his research on implicit and unconscious functioning suggests, and what I see echoed in session, is that a great deal of what looks like strategy in personality-disordered presentations is better understood as an automatic response pattern operating below conscious awareness, not a plotted maneuver (Westen, 1999). That doesn’t mean every behavior in every relationship is unconscious. It means the assumption of calculation deserves scrutiny rather than automatic acceptance.

This section can be misread in two opposite, equally unhelpful directions. The first: “so it’s never really manipulation, and I should just tolerate it.” Some people with HPD traits also manipulate consciously; a diagnosis doesn’t grant immunity from bad-faith behavior. The second: “so my partner is definitely doing this unconsciously, and I should extend unlimited patience.” That’s also not something I can tell Regina, or you, about a specific person from a blog post. Only a clinician who has actually evaluated someone, over time, can speak to what’s happening for that particular person.

Here is what I can say, with real limits attached: some HPD-associated behaviors may function as automatic regulation attempts rather than deliberate strategy. That’s a possibility worth holding, not a conclusion you can draw about a specific person from a diagnosis, a checklist, or a blog post. Intent isn’t observable from the outside, and it isn’t something this article, or any article, can determine for you. Theodore Millon, PhD, one of the field’s most influential personality theorists and longtime professor associated with the University of Illinois and later the University of Miami School of Medicine, described the histrionic presentation as built around an active, attention-dependent interpersonal style, in which some behaviors that look strategic may serve an underlying need for reassurance and approval (Millon Personality Group). His own clinical description uses the word “manipulates” alongside language about suggestibility and poor self-integration. It does not settle the question of intent for any individual person, and I want to be careful not to overstate what his framework can tell you about someone you know.

How This Can Look Like Gaslighting Without Being Gaslighting

Partners frequently describe the experience as gaslighting, and I understand why. The felt experience overlaps: confusion, self-doubt, a sense that reality keeps shifting underneath you. But clinically, gaslighting describes a pattern where someone deliberately manipulates another person into doubting their own perception, memory, or sanity, usually to gain power or avoid accountability. That’s a description of intent.

What often happens in HPD-affected relationships has a similar surface texture and a different engine. A person with pronounced histrionic traits may genuinely, in the moment, experience themselves as the wronged party, living inside a narrative that has already reorganized around their own emotional need, sometimes within minutes. The effect on the partner, doubting their memory of what just happened, can be identical to deliberate gaslighting. The mechanism is not.

Why does this distinction matter practically, and not only in theory? Because it changes what a partner can reasonably ask for. If a pattern is deliberate manipulation, the appropriate response usually involves firm boundaries, safety planning, and often an exit. If a pattern is unconscious dysregulation, the appropriate response might still involve firm boundaries, but the framing shifts, from “how do I outmaneuver someone who’s out to get me” to “how do I protect my own reality while someone I love struggles with something they may not fully see in themselves.” Both responses can include leaving. Neither requires the partner to become a forensic investigator of the other person’s intent, which is a job no partner is equipped to do and no partner should have to do.

The Patterns Partners Describe: Guilt, Crisis, Withdrawal, Triangulation

Across the clients I’ve worked with in this specific dynamic, certain patterns come up again and again, regardless of whether the underlying cause turns out to be HPD, another Cluster B presentation, general emotional dysregulation, or something else the person hasn’t been evaluated for. I want to describe these plainly, because naming a pattern is different from diagnosing a person.

Guilt induction. A partner ends up feeling responsible for the other person’s emotional state, often disproportionate to what actually happened. A late arrival becomes evidence of not caring. A quiet evening becomes evidence of falling out of love.

Manufactured or amplified crises. Something that could be a minor issue becomes an emergency requiring immediate, full attention. This isn’t always fabricated from nothing; often a real but modest problem gets emotionally inflated until it consumes the room.

Seduction and sudden withdrawal. Intense warmth gives way, sometimes within the same day, to coldness or distance, leaving a partner scrambling to understand what changed.

Triangulation. A third person, an ex, a friend, a sibling, gets pulled into the emotional narrative, which can intensify jealousy, competition, or urgency.

Victim positioning. In conflict, the narrative reorganizes so the person with the pattern experiences themselves, and presents themselves, as the one who was wronged, regardless of how the conflict actually unfolded.

What partners consistently report is the compounding effect of chronic self-doubt and hypervigilance: they start monitoring their own tone, their own timing, their own face, trying to prevent the next crisis before it starts. That vigilance is exhausting, and it’s real, whatever the underlying clinical picture turns out to be. It’s a close cousin of the hyperawareness I see in clients recovering from betrayal trauma, where the nervous system stays braced for a shift that may or may not be coming.

Roxana’s Spreadsheet: When a Partner Starts Building a Case

Roxana is 43, an architect, and she brings a spreadsheet to our third session. Not metaphorically. An actual spreadsheet, opened on her phone, columns labeled by date, incident, and what she calls “the flip,” the moment her partner’s story about an event changed from how she remembered it. “I need to know if I’m the problem,” she says. “I’ve started writing things down because I don’t trust my own memory anymore.”

Her partner, she tells me, had described a canceled trip to his mother as something Roxana had ruined by “not caring enough about family.” Roxana had, in fact, been the one who suggested rescheduling because of a work deadline she’d disclosed weeks earlier. By the next morning, in her partner’s retelling to his mother, Roxana had simply “decided not to go.”

“He wasn’t lying to hurt me,” she says, and then stops. “Or maybe he was. That’s the thing. I don’t know which one it is, and not knowing is worse than either answer alone.”

Sitting with Roxana that afternoon, I felt the particular strain that shows up in driven, detail-oriented clients trying to solve an emotional problem with an analytical tool. The spreadsheet wasn’t irrational. It was a reasonable response to an environment where her own perception kept getting contradicted. But a spreadsheet can catalog a pattern. It can’t resolve the question underneath it, which isn’t really “what happened,” it’s “can I trust what I remember,” and that question doesn’t get answered by more data. It gets answered, slowly, by rebuilding trust in her own perception outside the relationship, which is different work than proving a case.

What I’ve come to think of as the case-building phase is common in this population of clients: driven, competent women who default to gathering evidence because evidence has worked for them in every other domain of their lives. I don’t discourage the documentation entirely, sometimes it’s useful for a client’s own clarity, or for a future conversation with a lawyer or a couples therapist. But I also don’t let the spreadsheet become the whole plan. Roxana left that session with her phone still open to the same columns. She hadn’t decided whether to keep adding to it.

Both/And: The Behavior Can Be Unintentional and Still Require Boundaries

Both of these things are true at once, and neither cancels the other. A behavior pattern linked to HPD, or to emotional dysregulation more broadly, can be largely automatic and unconscious. And that same behavior can still be genuinely harmful, and still require firm boundaries, distance, or an end to the relationship. Understanding the mechanism behind a pattern is not the same as excusing its impact, and I want to be unambiguous about that, because this is the section clients most often want to hear as permission to stay in something painful.

For Regina, the both/and looked like this: she came to understand that her husband’s collapse-then-recovery cycle likely reflected genuine emotional volatility rather than a calculated attempt to control her reactions. That understanding didn’t change her decision to stop absorbing responsibility for his moods. She started saying, plainly, “I can see you’re upset. I’m not going to argue about whether I caused it.” The dysregulation didn’t need her to solve it. Her boundary didn’t require her to determine his intent first.

For Roxana, the both/and meant putting down the spreadsheet without deciding, once and for all, whether her partner had lied on purpose. She didn’t need a verdict to decide that the pattern of shifting narratives was unsustainable for her. “I don’t need to know if he meant it,” she told me eventually. “I need to know if I can keep living inside a story that keeps changing.” She hadn’t answered that question by the time our work together paused for the summer, and she told me she wasn’t in a hurry to force an answer before she was ready.

This is the part of the both/and that I think gets lost in a lot of pop-psychology content about personality disorders: compassion for the mechanism and accountability for the impact are not opposites. A partner can hold genuine understanding that someone’s nervous system is struggling, and still refuse to keep absorbing the consequences of that struggle indefinitely. Those two things belong in the same sentence, not in competing camps.

The Systemic Lens: Why “Dramatic Women” Get Diagnosed and Dismissed Differently

It’s worth naming the history sitting underneath this diagnosis, because HPD carries baggage that other personality disorders don’t carry in quite the same way. Histrionic Personality Disorder descends, in a documented clinical lineage, from the nineteenth-century diagnosis of hysteria, a label applied almost exclusively to women and used, for generations, to pathologize emotional expression, sexuality, and behavior that violated gendered expectations of restraint. That history doesn’t invalidate the current diagnostic criteria, which are behaviorally specific and gender-neutral on paper. But it does mean the label lands differently depending on who’s wearing it and who’s applying it.

A woman who is loud, emotionally expressive, and attention-seeking gets called histrionic. A man exhibiting comparable behaviors more often gets described in other terms, or overlooked diagnostically altogether; some clinical literature suggests HPD may be underdiagnosed in men partly because the criteria were shaped by, and are more readily recognized in, socially feminine-coded presentations. That’s a structural issue in how the diagnosis itself was built, not a fact about who actually has the underlying pattern.

This matters for a driven, professional woman like Regina or Roxana in a very specific way. If she’s the partner of someone with HPD traits, she’s often already fighting an uphill cultural battle to be believed, “he seems so charming,” “she must be exaggerating,” “are you sure you’re not overreacting.” The same cultural script that shaped the diagnosis’s history also shapes how seriously her account gets taken by friends, family, and sometimes clinicians who haven’t thought carefully about this pattern. Naming that structural bias doesn’t fix it. It does help a partner understand that her difficulty getting believed isn’t a personal failing; it’s a wider pattern she’s up against, similar to what I write about in the context of gaslighting recovery more broadly.

HPD, BPD, and NPD: Why the Differential Matters and Why It Isn’t Yours to Make

Cluster B personality disorders share surface features, attention-seeking, emotional intensity, relational instability, and get conflated constantly online. They are not interchangeable.

Borderline Personality Disorder centers on identity instability, intense fear of abandonment, and often self-harm or suicidality alongside relational volatility. Narcissistic Personality Disorder centers on grandiosity, a need for admiration, and a marked lack of empathy. Histrionic Personality Disorder centers on excessive emotionality and attention-seeking, without the core identity instability of BPD or the grandiosity of NPD. A person can also meet criteria for more than one, since personality disorders frequently co-occur.

Distinguishing between these presentations requires a full clinical evaluation, typically involving structured interviews, history-taking across a person’s whole adult life, and often collateral information, conducted by a licensed clinician trained in differential diagnosis. It cannot be done by a partner reading a blog post, watching a video, or filling out an online quiz about someone else’s behavior. If you’re trying to figure out what’s happening in your relationship, the accurate move isn’t to self-diagnose your partner from a checklist. It’s to get support for yourself, and if the relationship allows for it, to encourage your partner toward their own evaluation, which is a decision only they can make.

I’ll also say this plainly, because it needs to be said without hedging: emotional dysregulation, HPD traits, or any personality disorder never excuses abuse. If what’s happening in a relationship includes threats, violence, coercive control, or persistent deliberate cruelty, the clinical nuance in this article does not apply, and the priority is safety, not understanding someone’s inner mechanism. Nothing here is meant to talk a person out of recognizing danger, and if that’s where you are, my guide on recognizing relational trauma and abuse is a more direct place to start than this one.

What Actually Helps: Therapy, Coaching, and the Limits of Each

Clients often ask me what actually helps, both for the partner trying to stay grounded and, when relevant, for the person exhibiting the pattern. I want to answer that carefully, because these are two different kinds of support, aimed at two different problems, and conflating them creates confusion.

Individual therapy is the setting for treating a mental health condition, processing the specific pain of this relationship, and, if a person has HPD or a related diagnosis themselves, working on the underlying emotional regulation and self-worth patterns that drive the behavior. Marsha Linehan, PhD, professor emerita of psychology at the University of Washington and creator of Dialectical Behavior Therapy, developed an approach originally built for borderline presentations that has since informed broader work with emotional dysregulation across several personality disorders, centered on building concrete skills for tolerating distress and regulating intense affect (Linehan et al., 1991). That specific study evaluated dialectical behavior therapy for borderline personality disorder, not HPD directly, and I’m citing it because it’s the clearest evidence base for treating emotional dysregulation as a mechanism, not because it’s a validated HPD-specific protocol. Mentalization-based treatment is also used clinically with some Cluster B presentations, though the evidence base for HPD specifically is thinner than for BPD, and any claim that a specific therapy reliably reduces manipulative behavior in HPD deserves real skepticism until a person’s own clinician, working with that person directly, determines what fits.

Executive and personal coaching, which is the work I also do, is not trauma treatment and not a substitute for therapy. If you’re the partner trying to stay clear-headed while loving someone with this pattern, coaching can help you build decision-making frameworks, strengthen boundaries in your professional and personal life, and stay oriented toward your own goals rather than getting fully absorbed into managing someone else’s emotional weather. It does not diagnose, and it does not treat a personality disorder, in you or in anyone else. If what you need is processing genuine relational trauma, grief, or a mental health condition, that’s therapy’s job, and I’ll say so directly if that’s what a client needs, even in a coaching context.

Ramani Durvasula, PhD, clinical psychologist and author of Should I Stay or Should I Go?, writes about the exhausting vigilance partners develop in relationships marked by unpredictable emotional shifts, describing the felt experience as something close to permanent bracing (Durvasula, 2017). What I add to that from my own clinical work is this: bracing is a nervous system’s reasonable response to genuine unpredictability. It is not a character flaw in the partner, and it is not proof that the partner is imagining the problem. It’s also not sustainable indefinitely, which is usually the actual reason someone ends up in my office.

Recovery, for the partner, rarely means fully explaining or resolving the other person’s pattern. It usually means something narrower and more achievable: rebuilding trust in your own perception, deciding what you will and won’t absorb going forward, and getting support, whether that’s individual therapy, coaching, or both, for the specific toll this relationship has taken on you. That’s a realistic goal. “Understanding exactly why he does this” often isn’t, and chasing it can become its own kind of exhausting, unfinished project, the same way I caution clients against turning their own healing work into another performance review of someone else’s behavior.

If this resonates and you’re trying to sort through a relationship like this, individual therapy is available for processing the impact directly, and executive coaching is available for driven professionals who want structured support for boundaries and decision-making alongside, not instead of, clinical care when that’s what’s needed. You’re welcome to reach out and find the right fit.
