When You Still Miss the Sociopath: Trauma Bonds, Intermittent Reinforcement, and Grief

Sociopathy & Antisocial Personality Disorder • May 14, 2026

When His Number Still Lights Up Something Inside You

It’s a Tuesday in late October. Camille is standing at her kitchen counter in her West Elm sweatpants, the kettle hissing behind her, the last of the dusk light slanting across the marble. She’s a 39-year-old VP of product at a Series C startup. She has a calendar full of one-on-ones tomorrow and a deck due Thursday. By every external measure, she is fine.

Then her phone lights up — a Twitter notification, not him — and her chest still seizes the way it used to when his name appeared. She hasn’t seen him in eleven months. She knows, with the cold clarity of someone who’s read the books and done the work, that he was a sociopath. He lied without effort. He weaponized her vulnerabilities. He left bruises that didn’t show.

And yet. There is a particular Sunday morning — coffee, his hand on the small of her back, a joke about her mother — that she can’t stop returning to. She misses him. Not the version who screamed at her in the rental car in Sonoma. The other one. The one who, for about ninety seconds at a time, made her feel like the most known person in the room.

In my work with driven, ambitious women who’ve left sociopathic partners, this is the question that brings them back to the consultation room months after the breakup: Why do I still miss him? What is wrong with me?

Here’s what I want you to hear before we go any further: nothing is wrong with you. Missing someone who harmed you isn’t a character flaw, a moral failure, or evidence that you secretly want to go back. It’s a neurobiological fingerprint left by a very specific kind of relational damage — and there’s a name for it. We’ll spend this post unpacking that name, the science beneath it, and the slow body-based work of healing without returning.

What Is a Trauma Bond?

The phrase “trauma bond” gets thrown around loosely on social media, often confused with “toxic relationship” or “codependence.” Clinically, it’s something far more specific — and far more important to name accurately if you want to heal from one.

A trauma bond isn’t proof that you loved badly. It’s evidence that your nervous system tried to survive an impossible situation by attaching itself to the source of the danger. That’s not a flaw in your wiring. That’s your wiring working exactly as evolution designed it to — just under conditions it was never meant to handle.

Sociopathy — clinically captured under the diagnosis of Antisocial Personality Disorder (ASPD) — involves a pervasive pattern of disregard for others’ rights, deceitfulness, impulsivity, and lack of empathy or remorse. Researchers including Adrian Raine, PhD, neurocriminologist at the University of Pennsylvania, have spent decades mapping the neurobiology of these traits. What matters for our purposes is this: when you’re in relationship with someone who can mimic care without feeling it, your nervous system gets a master class in unpredictability. And unpredictability is the soil where trauma bonds grow.

It’s worth saying clearly: trauma bonds aren’t unique to romantic relationships with sociopaths. They form between children and abusive parents, between hostages and captors, between members and cult leaders. The common ingredient isn’t romance. It’s the cycle — danger, then relief, then danger again — delivered by the same hand. If you grew up in a family where this pattern was already familiar, the adult version can feel less like a red flag and more like home, which is one of the cruelest dynamics I see in my practice.

The Neurobiology of Intermittent Reinforcement

To understand why you still miss the sociopath, we have to talk about your dopamine system — and specifically about why your brain finds unpredictable rewards more compelling than reliable ones.

This is the genius of the slot machine, and it’s the cruelty of the trauma bond. Both run on the same neurobiology.

Bessel van der Kolk, MD, psychiatrist and trauma researcher at Boston University, author of The Body Keeps the Score, has written extensively about how trauma is stored not just in cognition but in the body’s autonomic nervous system. When you’re in relationship with someone whose mood and behavior shift without warning, your body never gets to fully exhale. You exist in a chronic state of low-grade scanning — eyes on the front door, ears tuned for the change in his voice, stomach permanently in a half-flinch. That state has a name, and it has a neurobiology.

Stephen Porges, PhD, distinguished university scientist at Indiana University and originator of Polyvagal Theory, describes the body’s social engagement system as the part of the nervous system that calms us through connection. In safe relationships, presence with another person down-regulates the threat system. In trauma-bonded relationships, the opposite happens: the body learns that the same person who triggers the threat is the only one who can turn it off. So your nervous system runs toward them and away from them at the same time. It’s exhausting. It’s also why you can’t simply decide to stop missing him.

And then there’s betrayal trauma. Jennifer Freyd, PhD, psychologist and researcher who coined the term betrayal trauma at the University of Oregon, has shown that when harm comes from someone you depend on for safety, connection, or survival, the brain often suppresses awareness of the harm in order to preserve the attachment. That suppression doesn’t just disappear when you leave. It surfaces later as longing, intrusive memories, and a confusing pull toward the person who hurt you — what Freyd’s work helps us understand isn’t pathology, but the cost of attachment under impossible circumstances. We unpack this in depth in our complete guide to betrayal trauma.

What I want you to take from this section: the missing isn’t a referendum on your judgment. It’s chemistry. And chemistry, like any biology, can be worked with — slowly, somatically, and with a great deal of compassion.

How Trauma Bonds Show Up in Driven Women

The women I work with are some of the most discerning humans I’ve ever met. They are physicians who can read a chart in fifteen seconds. They are operators who can spot a misaligned incentive on slide three of a pitch deck. They are mothers who know the exact tone shift in their child’s voice that means something is wrong.

And then they tell me they didn’t see it. They tell me they’re embarrassed. They tell me they should have known.

What I see consistently is this: the same nervous-system architecture that makes a woman brilliant at her job — the hyperattunement, the pattern recognition, the willingness to keep trying — is the architecture that gets weaponized inside a trauma bond. Driven, ambitious women aren’t more naive. They’re often more committed. They’re trained, professionally and often relationally, to solve hard problems by working harder. A sociopathic partner becomes the hardest problem they’ve ever encountered, and their relentlessness becomes the rope.

Camille — the woman from our opening scene — came to me eight months after she’d ended things. She was sleeping four hours a night. She’d taken the long way home from her gym for a year so she wouldn’t drive past his block. She had a folder on her desktop called “Receipts” where she kept screenshots of his lies, and she opened it three or four times a day, not to feel vindicated but to remind herself the relationship had been real. She didn’t trust her own memory anymore. That’s what coercive control does — it doesn’t just hurt you, it erodes the instrument you’d use to measure the hurt.

What Camille was experiencing wasn’t ambivalence about going back. She had no intention of going back. What she was experiencing was the lived neurobiology of a trauma bond in active withdrawal: intrusive memories of the rare tender moments, somatic cravings that didn’t make logical sense, shame that she was still thinking about him at all. The shame was the loudest part. Driven women rarely struggle with admitting they were hurt. They struggle, ferociously, with admitting they’re still affected.

In my practice, I see this pattern across professions. Physicians who saved other people’s lives all day and came home to a partner who told them they were stupid. Founders who pitched venture firms on Monday and absorbed devastating verbal cruelty on Monday night. Lawyers who could cross-examine a hostile witness and then defended their partner’s behavior to their best friend. The competence outside the relationship is real. The trauma inside it is also real. Both can be true. That’s the heart of trauma-informed work — and it’s the work we do together inside therapy with Annie.

Grieving Someone Who Never Fully Existed

There’s a particular kind of grief that follows a sociopathic relationship, and it doesn’t get named often enough. It isn’t the clean grief of losing someone who loved you and died. It isn’t the angry grief of a betrayal you saw coming. It’s something stranger and harder: you’re mourning a person who, by all clinical evidence, never fully existed.

The man Camille missed at her kitchen counter on that October Tuesday — the one with his hand on the small of her back, the one who laughed at her mother joke — that man was real for ninety seconds at a time. But the architecture beneath him wasn’t a misunderstood good guy having a bad day. It was a person without the capacity for the kind of empathy she’d assumed was underneath. The good moments weren’t a window into who he really was. They were a tool. That’s the part the body can’t quite metabolize.

When I sit with clients in this grief, what I often hear is something like: I’m not mourning him. I’m mourning the version of him I built in my head from the breadcrumbs. That mourning is real. It deserves space. It also deserves the truth: the breadcrumbs were a feature of the harm, not evidence of an inner self that could have grown into more.

This is where the work of Pauline Boss, PhD, professor emeritus at the University of Minnesota and the clinician who developed the concept of ambiguous loss, becomes essential. Ambiguous loss is grief without closure — grief that doesn’t have a clean ending, a body to bury, a verifiable cause of death. Mourning a sociopathic partner is, by definition, ambiguous. There’s no funeral. There’s no shared community that holds the truth of what happened. There’s just you, at your kitchen counter, missing someone who may have looked you in the eye and lied every day you knew him.

The body is slower than the mind here. Your prefrontal cortex can hold the full clinical picture — manipulative, exploitative, dangerous — while your limbic system, the older, deeper, more emotional brain, still mourns. Both are operating in good faith. Neither is wrong. The work isn’t to argue your body out of its grief. The work is to let the grief move through, slowly, without using it as evidence that you should call him.

I tell clients: grief doesn’t mean go back. Grief means something in you was real, even if what met you wasn’t. Honoring that — without rewriting history to make him deserve the honoring — is one of the most exquisite, painful pieces of work this kind of recovery asks of us.

Both/And: The Love Was Real AND The Person Was Not Safe

One of the most stabilizing frames I offer clients in this terrain is the both/and. Trauma recovery doesn’t ask you to choose between competing truths. It asks you to hold them — both of them — at the same time, without letting either collapse the other.

The love was real. Your capacity to love, to bond, to attach, to hope — every bit of that was real. None of it was naive. None of it was stupid. It was you, doing what humans were built to do.

AND. The person was not safe. The person was not, by clinical definition, capable of meeting you the way you tried to meet them. The relationship was structurally incapable of being what you wanted it to be — not because of anything you failed to do, but because of who he was.

Both of these things are true. Healing requires you to stop alternating between them — one day “the love was real, maybe I should reach out,” the next day “he was a monster, I’m an idiot for missing him” — and start holding them simultaneously. The love was real AND the person was not safe. Both. Always. No collapse.

Let me show you what this looks like in a body.

Leila is a 44-year-old surgeon. She left a five-year relationship with a sociopathic partner two years ago. She’s done EMDR. She’s read everything. She’s a brilliant clinical thinker who, by every external metric, has “moved on.” But here’s what she described in our session last spring:

She was in the produce section of her neighborhood grocery store on a Saturday morning, reaching for a clamshell of raspberries, when she caught a particular note of cologne from a man two carts away. Not his cologne. Like his cologne. Her stomach dropped. She put the raspberries back. She walked to the parking lot. She sat in her car for fourteen minutes before she could drive home.

In our session, she said: “I don’t want him back. I want my Saturday morning back.”

That’s the both/and in real time. The not-wanting-him is true. The losing-her-Saturday is also true. Healing isn’t about no longer having the body response. It’s about her nervous system slowly learning that the body response is information about the past, not a command for the present. She put the raspberries back. She didn’t pick up the phone. That’s the work.

Janina Fisher, PhD, psychologist and trauma specialist, faculty at the Trauma Research Foundation, has written extensively about how the parts of us shaped by trauma don’t disappear when we leave the trauma. They keep showing up — in cologne aisles, in Tuesday-evening dusks, in the second before sleep. The both/and lets us greet those parts with compassion instead of contempt. Yes, I miss him AND I’m not going back. Yes, my body is responding AND I am safe now. That sentence, said often enough, eventually becomes true at the level of biology.

The Systemic Lens: Why Culture Tells You to “Just Get Over It”

If you’ve tried to explain a sociopathic relationship to someone who hasn’t been inside one, you’ve probably encountered the well-meaning brutality of “but why didn’t you just leave?” Or, after you did leave: “Why are you still talking about him?” Or, the cruelest one: “Maybe you should focus on the positive.”

The cultural script around abusive relationships is breathtakingly inadequate, and it’s worth naming the systemic reasons why. It isn’t just that the people around you are unkind. It’s that the entire cultural frame for “real” abuse is built around bruises and police reports, not around the slow, invisible architecture of psychological coercion that defines sociopathic harm.

Evan Stark, PhD, forensic social worker and author of Coercive Control, has spent his career arguing that the legal and cultural definition of intimate partner abuse misses the actual mechanism of harm in most cases. Sociopathic and coercively controlling partners rarely leave the kind of evidence the culture knows how to recognize. They leave women who feel crazy, who can’t sleep, who don’t trust their own memory, and who have to explain — over and over — why the missing is so hard. That explanation gap is, itself, a form of secondary harm.

There’s also the gendered cultural script: women are supposed to be relational, forgiving, capable of seeing the good in people. The same qualities that culture celebrates in a “good woman” are the qualities a sociopath exploits to keep her engaged. And then, when she leaves, the same culture tells her she should be “over it” — as if her hyperattunement to others’ suffering, the very thing she was praised for, is now a problem she should have outgrown by month four.

For driven, ambitious women, there’s a specific overlay: high-functioning recovery. The cultural expectation is that if you can run a company, manage a team of forty, or get through a residency, you should be able to “manage” your post-relationship grief. So women hide it. They show up to board meetings with mascara that smudged in the car. They take 6 a.m. calls from the floor of their bathroom. They tell their best friend they’re “doing great.” And then they come into my office and finally exhale.

Inside Fixing the Foundations, my course for relational trauma recovery, we name this directly: high-functioning isn’t healed. The performance of okayness isn’t the same as the lived experience of safety. And there’s no version of recovery that asks you to stop missing him on a culturally acceptable timeline. The timeline is the body’s. The body’s timeline is slower than the culture’s. That’s not a flaw in you — it’s a flaw in the cultural script.

When clients ask me, “When will this stop?”, I answer honestly: longer than you want, but not as long as you fear. The missing fades — not because you force it, but because the new patterns of safety you’re laying down, week by week, eventually outweigh the old patterns. The dopamine system can be retrained. The body can learn. But it learns at its own pace, in its own language, and the work is to stop fighting that pace.

How to Heal Without Going Back

Healing from a trauma bond isn’t an event. It’s a slow accumulation of small somatic, relational, and behavioral choices that, over time, retrain your nervous system to no longer crave the source of the harm. Here’s what that actually looks like in clinical practice.

First: name what happened, in clinical language. Vague language keeps you stuck. “It was complicated” doesn’t help your nervous system. “I was in a relationship with someone who exhibited sociopathic traits, and my nervous system formed a trauma bond” — that does. The specificity isn’t to pathologize him. It’s to liberate you from the story that what happened was love poorly handled. It wasn’t. It was harm, structured around moments of relief.

Second: track the cravings without acting on them. When the urge to text him rises, don’t argue with it. Don’t shame it. Notice where it lives in your body. (For most of my clients, it’s the chest, the throat, or a strange warmth in the hands.) Notice what triggered it — a song, a date, a particular kind of light. Then do something small that interrupts the loop without pretending the loop isn’t real. Walk around the block. Text a specific friend who knows. Drink a glass of cold water. The point isn’t to feel better. The point is to not pick up the phone.

Third: do the body work. Talk therapy alone, in my experience, rarely fully resolves a trauma bond. The bond lives in the autonomic nervous system, which doesn’t speak in words. Modalities like Somatic Experiencing (developed by Peter Levine, PhD), Sensorimotor Psychotherapy (Pat Ogden, PhD), EMDR (Francine Shapiro, PhD), and Internal Family Systems (Richard Schwartz, PhD) all work with the body and with the parts of the self formed under threat. Find a trauma-informed clinician who works in one of these modalities. If you’re not sure where to start, you can connect with my practice for a referral or a consult.

Fourth: build new patterns of safety, slowly. Your nervous system needs new evidence — actual, lived, repeated evidence — that connection can be safe. This usually doesn’t mean a new romantic partner. It means safe friendships, safe community, safe interactions with your own body. It means a yoga class where the teacher knows your name, a Sunday morning ritual that no one else gets to interrupt, a therapist’s office where you don’t have to perform. These small safeties, accumulated, become the new baseline.

Fifth: grieve, with witnesses. Grief in private becomes shame. Grief witnessed becomes integration. Find one or two people — a therapist, a survivor friend, a support group — who can hear “I still miss him” without flinching, fixing, or explaining. Being witnessed in the both/and is one of the most reparative experiences in this kind of healing.

Finally: be patient with the timeline. Most women I work with start to feel the trauma bond loosen between months nine and eighteen of consistent, body-based, witnessed work. The longing doesn’t vanish — it becomes background instead of foreground. You can stand at the kitchen counter on a Tuesday in October and notice the memory and let it pass, the way you’d watch a leaf drift down a stream. The leaves don’t stop. The pull they have on you does.

If you’re in this terrain right now — if you’re missing him today, and the missing feels like proof that something’s wrong with you — please hear this. Nothing is wrong with you. You loved with the whole of yourself. The harm you survived was structural, not personal. And the work of healing, while slow, is real. You can work one-on-one with me, take the quiz to identify what’s underneath, or join the newsletter for the kind of Sunday note that meets you where you actually are.

You don’t have to stop missing him to be free. You just have to stop letting the missing make the decisions.
