Triangulation: How Narcissists Pit People Against Each Other

NARCISSISTIC ABUSE • April 24, 2026

When You Started Competing for Something That Should Have Been Yours

You remember the exact moment it started. You were telling him about a promotion you’d just been offered—not bragging, just sharing, the way people who are building a life together share things—and he mentioned, in the same neutral tone he used to read weather reports, that his colleague’s wife had just made partner at a firm twice the size of yours. The implication hung in the air, shapeless enough to deny but pointed enough to land exactly where he intended.

You filed it. Decided you were being sensitive. But something shifted that evening—something small and structural. You started managing how you talked about your work. You started softening your wins, scanning his face before you finished a sentence, calibrating how much pride you were allowed to take up in any given room. You weren’t even aware you were doing it. You were just—careful. You told yourself that was love. The consideration of a partner.

It wasn’t love. It was the beginning of triangulation. And the most insidious thing about it is that by the time you realize you’ve been competing—for affection, for approval, for the basic sense that you’re enough in your own relationship—you’ve often been doing it for years.

Triangulation is one of the most reliably disorienting tactics in the narcissistic abuse toolkit. It doesn’t require overt cruelty. It requires only the strategic introduction of a third party, real or implied, into the space between two people. Once the third corner of that triangle is in place, the narcissist occupies the center—where all roads lead back to them.

What Is Triangulation?

Murray Bowen’s foundational work on family systems gives us a clinical vocabulary for what people in narcissistic relationships often describe as a persistent, queasy feeling that they’re never quite winning—and can’t figure out what game they’re even playing. In healthy relationships, the third element in a triangle might be a trusted friend or therapist: someone who provides perspective and diffuses anxiety without becoming a weapon. In narcissistic systems, the third element is a tool of control.

The third corner of the narcissist’s triangle might be:

• An ex-partner referenced with telling frequency, usually in flattering terms that create implicit comparisons
• A colleague or rival whose achievements are mentioned in ways that invite you to feel insufficient
• A family member who is positioned as the reasonable one—the one who agrees with the narcissist, the one who doesn’t “overreact”
• A vague social other (“everyone agrees with me,” “my friends all think you’re being difficult”) whose existence cannot be verified or challenged
• Children in parenting contexts, used as messengers, informants, or emotional pawns between estranged partners

What all of these have in common: they’re deployed to ensure that your emotional energy is never fully present in the direct relationship. It’s always partially borrowed by the triangle. Partially occupied by trying to understand your position relative to someone who isn’t even in the room.

The Psychology Behind Why It Works

Triangulation is effective not because it’s sophisticated—it’s actually quite old, and most people have some cognitive awareness of jealousy as a manipulation tool—but because it operates primarily on the attachment system, not the rational mind. Your intellect can know that the comparison is unfair. Your nervous system doesn’t care.

Ramani Durvasula, PhD, clinical psychologist and researcher specializing in narcissistic personality disorder and narcissistic abuse recovery, author of It’s Not You: Identifying and Healing from Narcissistic People and Don’t You Know Who I Am?, identifies covert narcissism—with its quiet resentments and passive-aggressive deployment of comparisons—as among the most difficult forms of triangulation to name precisely because it’s delivered with such plausible deniability. The covert narcissist doesn’t announce the comparison; they drop it, gently, into an otherwise neutral conversation. The receiver walks away feeling something, but can’t point to anything that was overtly said.

The psychological mechanisms triangulation exploits include:

• Attachment anxiety: Particularly potent for anyone with an anxious or fearful-avoidant attachment style, triangulation activates the fear of abandonment at a preconscious level, triggering protest behaviors—increased closeness-seeking, heightened monitoring of the partner’s attention—before conscious awareness catches up.
• Social comparison theory: Leon Festinger’s foundational work on social comparison demonstrates that humans automatically evaluate themselves relative to relevant others. Narcissists exploit this by ensuring there is always a relevant other being introduced.
• Intermittent reinforcement: The same mechanism that underlies trauma bonding—unpredictable reward schedules—operates in triangulation. Sometimes the narcissist’s attention is full and warm. Then the third party appears. The alternation between security and threat creates a neurobiological dependence on the moments of security that mirrors substance dependency patterns.

Peter Fonagy, PhD, FBA, psychoanalyst and Professor of Contemporary Psychoanalysis and Developmental Science at University College London, whose mentalization-based framework illuminates how relational trauma impairs our ability to read others’ mental states accurately, would frame the triangulated person’s predicament this way: when your attachment system is under threat, your capacity for mentalization—for holding your own mind and the other’s mind in view simultaneously—contracts. You become less able to think clearly about what’s happening, precisely when clear thinking is most needed.

This is not a failure of intelligence. It’s a feature of neurobiology under relational stress.

How Triangulation Shows Up in Driven Women’s Relationships

In my work with clients, I see triangulation produce a particular kind of damage in driven and ambitious women—one that’s distinct from the ordinary jealousy the tactic might produce in other contexts. These are women who have built their professional lives on clear thinking, measurable results, and the sense that effort and quality produce predictable outcomes. Triangulation corrupts all three of those operating assumptions.

The driven woman in a triangulated relationship often intensifies. She works harder to be indispensable. She monitors more carefully. She produces more—more attentiveness, more generosity, more accommodation—in an implicit competition she hasn’t consciously agreed to enter. And because she’s genuinely competent and genuinely caring, her efforts sometimes produce temporary improvements in the narcissist’s warmth, which reinforces the belief that the right combination of inputs will solve the problem. It won’t. The problem isn’t her performance. The problem is the system.

Jordan is a 46-year-old chief marketing officer at a consumer brand—precise, data-oriented, deeply relational. She’s been in a relationship with her partner for six years. She’s also spent roughly five of those six years in varying degrees of competition with his ex-wife—a woman she’s never met, who her partner references in a way that always carries an implicit edge. “She never minded when I traveled for work.” “She understood that my industry has its rhythms.” Each reference is delivered neutrally, as though it’s information, as though he’s simply contextualizing. Jordan knows, at some level, what’s happening. She’s a marketing person; she’s read about psychological manipulation. And she still finds herself, on the Sunday evenings before he travels, softening her requests, swallowing her frustrations, trying to be the version of herself that would make the comparison unnecessary.

That internal adjustment—the constant recalibration—is what triangulation costs. Not just the emotional bandwidth. The self. The gradual erosion of knowing what you actually want and feel, underneath the continuous effort to be enough relative to a moving target you didn’t set.

Kira, a 31-year-old associate at a private equity firm, experienced a different flavor of triangulation: workplace-adjacent, organized around professional comparisons. Her manager—who she now recognizes as having significant narcissistic traits—had a habit of mentioning a former direct report’s work in meetings where Kira’s contribution was being evaluated. “Alex used to approach this differently,” delivered with a quality of wistfulness that made the room slightly colder. She started arriving earlier, staying later, revising work that didn’t need revision. She thought she was demonstrating commitment. She was demonstrating that the tactic had worked.

The Third Corner: Who Gets Used and How

One of the most important things to understand about triangulation is that the third party—the ex, the colleague, the “everyone who agrees with me”—is also being used. They may not know it. They may not be willing participants. But they’ve been assigned a role in a dynamic they didn’t author.

This matters for several reasons. First, it means the problem isn’t actually about the third party. It never was. The narcissist could replace them with anyone; the specific person is almost interchangeable. What matters is the function they serve—destabilization, comparison, implied threat of replacement. Understanding this can be profoundly clarifying: you were never actually competing with that person. You were being asked to compete, and the competition was rigged from the start.

Second, and particularly relevant for those navigating co-parenting with a narcissistic ex, children are sometimes used as the third point of the triangle. This is among the most harmful deployments of the tactic because children don’t have the cognitive or psychological resources to recognize that they’re being positioned, and the loyalty conflicts it creates can produce lasting attachment disruption. If you’re in this situation—if you’ve watched your children come home from the other parent’s home reporting things that feel designed to undermine your relationship with them—you’re likely experiencing narcissistic triangulation through co-parenting. That particular form requires its own specific navigation, and it’s worth seeking specialized therapeutic support.

Third, recognizing the instrumentalized third party can help rebuild the empathy you may have lost for yourself. If the people being used as comparison points are also, in some sense, being used—then you were never the problem. You were the target. There’s a meaningful difference.

Both/And: You Were Perceptive and You Were Being Manipulated

Here’s the thing about triangulation that I want to hold clearly in both hands: you almost certainly sensed something was off. The perceptiveness that makes driven women exceptional at their work—the ability to read a room, to notice subtext, to track relational dynamics with precision—was probably registering data from the start. You felt the shift when the third party was mentioned. You noticed the particular quality of the comparison. You recognized, even if you didn’t name it, that something was being done to you.

And at the same time: you couldn’t quite locate it well enough to respond to it. That’s not a failure of intelligence. That’s the specific design of the tactic. Triangulation is constructed for plausible deniability. Every individual instance can be explained away. The pattern requires time, accumulation, and perspective to see.

Both things are true: you were perceptive, and you were being deliberately confused. You saw something real, and the real thing was being actively obscured. This is the Both/And at the core of triangulation’s aftermath—not “I should have known” but “I did know something, and I was also working against a system designed to make knowing insufficient.”

What I see consistently in my work with clients who’ve been in triangulated relationships is that the recovery task isn’t rebuilding trust in other people. It’s rebuilding trust in yourself. Specifically, trust in your perceptions—the same perceptions that were doing their job all along, sending signals you were taught to second-guess.

The Systemic Lens: Why This Tactic Thrives in Ambitious Circles

Triangulation doesn’t exist in a vacuum. It’s a relational tactic, but it’s also a cultural one—and it lands with particular force in professional and social environments that already normalize comparison, competition, and the constant evaluation of relative worth.

Driven and ambitious women operate in systems that have been explicitly organized around comparative metrics: performance reviews, rankings, market positioning, peer benchmarking. The professional world has trained them to understand their value in relational terms—relative to others, relative to prior periods, relative to a benchmark someone else defined. A narcissistic partner or parent who introduces triangulation into an intimate relationship is exploiting a relational grammar that ambitious women have been practicing for years.

There’s also a gender dimension worth naming. Research on social comparison in intimate relationships consistently finds that women are more likely than men to be the targets of deliberate social comparison tactics, and that comparison-based manipulation is a documented feature of coercive control. Evan Stark, PhD, sociologist and researcher at Rutgers University School of Public Affairs and Administration, author of Coercive Control: How Men Entrap Women in Personal Life, situates triangulation within the broader architecture of coercive control: it doesn’t have to produce physical harm to produce significant psychological damage. The damage is in the steady erosion of the target’s sense of self-worth, self-trust, and independent identity.

The ambitious woman is also, paradoxically, more vulnerable to a specific flavor of this dynamic: the triangulation that targets her competence. When the narcissist introduces a comparison that implies she’s professionally insufficient—her work isn’t as meaningful, her success isn’t as impressive, her judgment isn’t as sound—it lands on the very self-concept she’s worked hardest to build. That’s not accidental. Narcissists are remarkably effective at locating the thing a person values most and using it as a lever.

How to Disentangle from Triangulated Dynamics

Disentangling from triangulation requires something that feels counterintuitive at first: less focus on the third party, and more focus on the pattern. The ex, the colleague, the “everyone”—they’re not the problem to solve. The structure is the problem. And restructuring your relationship to the structure starts with recognizing it clearly enough to stop responding to it as though it’s about the content.

Practically, this looks like:

• Naming the pattern, not the instance. When a comparison surfaces, instead of engaging with the specific comparison—defending yourself, explaining, trying to outcompete—notice: this is the pattern. You don’t have to say it aloud. You just have to stop letting the specific instance capture all of your attention.
• Refusing the implicit competition. This doesn’t require confrontation. It requires an internal reorientation: you’re not in a competition, and you don’t have to perform as though you are. That internal refusal interrupts the mechanism without requiring the narcissist to change.
• Returning to your own baseline. Triangulation works by making you perpetually other-focused—focused on the third party, on the narcissist’s attention, on the comparison. The antidote is reconnecting, regularly and deliberately, with your own interior: what do you feel, what do you want, what do you observe? Somatic practices—breathwork, body-based awareness, movement—can be particularly effective here because they return you to your own body before the analytical mind starts negotiating.
• Seeking mirroring from safe others. Triangulation isolates. It’s designed to. Part of what makes it so effective is that it turns the relationship into the only relevant reference point. Rebuilding relationships with people who can offer you accurate, caring reflection of who you actually are is not a luxury—it’s clinically necessary.
• Working with a trauma-informed therapist. The patterns that make triangulation sticky—attachment anxiety, the comparison-based self-evaluation that may have preceded this relationship—don’t resolve through insight alone. They need the consistent, attuned relationship that good therapy provides.

If you’re still inside a triangulated relationship, the question isn’t whether you can outperform the competition. The question is whether this is a relationship in which your fundamental worth is recognized without performance. That’s a question worth sitting with, as honestly as you can manage, with support.

And if you’ve already left—if you’re in the recovery phase, trying to understand why you worked so hard in a competition you didn’t know you’d entered—please know this: the effort you made wasn’t foolish. It was what you do when you’re a person who believes in working for the things that matter. The tragedy of triangulation is that it takes that belief and borrows it for a system that didn’t deserve it. Redirecting that belief—toward yourself, toward relationships that are actually equitable—is the work ahead. And it’s entirely possible.

If you recognize the patterns in this post and you’re ready to understand them more deeply—not just cognitively, but in your body and your relationships—reach out to schedule a consultation. You don’t have to decode this alone.
