Two Ways of Understanding Betrayal: Betrayal Trauma vs. Attachment Trauma: What's the Difference?

Written by Kris Cristiano

If you're in therapy or reading anything about your partner's betrayal, you've probably been handed more than one explanation for what's happening to you. Your therapist probably says you're dealing with PTSD symptoms and are traumatized. Something you’re reading might say you're dealing with an attachment injury. A podcast says you're experiencing betrayal blindness. Huh? What is it? And what do all of these ideas even mean?

These are all different models, and knowing the difference can change how you read your own reactions and what you ask for in treatment.

What a Therapy Model is (and why it matters to you)

A model is a map. It takes something messy and complex, like what happens inside a person when the one they love most lies to them, and draws a simplified picture so you can find your way around.

Every map leaves things out. A road map shows highways and skips elevation. A hiking map shows elevation and skips gas stations. Neither is wrong. They answer different questions.

Therapy models work the same way. The model your therapist uses decides which symptoms they will treat as the main problem. A therapist working from a map that shows only your anger will treat your anger. A therapist whose map only shows your fear of losing the relationship will treat that too.

That's the practical reason this matters. The model shapes the treatment you get.

The Betrayal Trauma Model Focuses on PTSD and Betrayal Blindness

Psychologist Jennifer Freyd introduced betrayal trauma theory in the early 1990s. Her question started with memory: why do some people who were harmed by someone close to them not know, or not fully remember, what happened?

For example, if a child depends on a caregiver for survival, noticing that the caregiver is harming them creates an impossible dilemma: the child depends on the caregiver for survival. So the child’s mind may keep the information out of awareness. Freyd coined the term betrayal blindness to describe this.

Freyd's early work focused on childhood abuse. Many clinicians have since applied her research to adult relationships, including infidelity and sexual betrayal, where a partner may depend on the other person emotionally, financially, and/or socially.

For a betrayed partner, this model offers one answer to the question: How did I not know? (and) Why didn’t I say something about the things that I did see? You weren't naive or stupid. Your mind may have done what minds do when the truth feels unsafe. It also gives a name to what many partners describe afterward: the fog, the shoving away of the things they did see, or the not seeing at all.

Like all models, this has its limits. It was built to explain unawareness, so it says less about the constant alertness partners feel after discovery, or about why the pull toward and away from your partner feels so intense.

The Attachment Model Explains Why It Hurts the Way It Does

John Bowlby, a British psychiatrist, spent decades on a different question: why do human beings bond, and what happens when bonds break? In his trilogy Attachment and Loss (1969 to 1982), he argued that closeness to a caregiver is a survival need, and that early experiences with that caregiver form an internal working model, or a mental blueprint for: 1) am I worthy of love and care? and 2) can I count on others in times of distress?

Mary Ainsworth turned the theory into something researchers could observe. Her Strange Situation procedure revealed that children respond to a caregiver's availability in distinct patterns: secure, anxious, and avoidant. Later, Mary Main and Judith Solomon identified a fourth, disorganized attachment, which appears when the caregiver is both the source of comfort and the source of fear. Researchers describe the child's disorganized attachment as fright without solution: the safe place and the danger are the same person.

Michelle Mays, LPC, CSAT-S, built her Attachment-Focused Partner Betrayal Model on this idea. Her work describes what she calls the betrayal bind: a partner who is your primary source of safety suddenly becomes a source of danger and pain. And yet, connection is also what healing needs. Your attachment system pushes you toward your partner. Your threat system pushes you away. Both are firing off at once.

That's why you can cry in your partner's arms one day and want him out of the house the next. You’re not broken! Your nervous system is being pulled in two directions at once.

Where the two models overlap

Both models say 1) we need each other to survive, and 2) the people we depend on can hurt us most. Both say that the whole spectrum of how betrayed partners act after betrayal, i.e., staying, numbing out, people-pleasing, phone checking, are all attempts to stay safe. In Freyd's own writing, betrayal trauma theory predicts that dissociation is shaped by the threat information poses to the attachment system. The two models aren’t necessarily rivals, but they’re built to help frame two different injuries. One to self, and the other to your partner. 

Where They Differ

Betrayal Trauma Model

  • Main question: Why didn't I see or register it?

  • Main cause: Selective awareness to protect a needed relationship

  • What it tries to explain: Fog, minimizing, gaps in memory, self-doubt

  • Treatment focus: Restoring clarity and trust in your own perception

Attachment Model

  • Main question: Why does losing this bond feel so dangerous?

  • Main cause: Internal working models and attachment strategies

  • What it tries to explain: Push and pull, fear of abandonment, shame, old wounds

  • Treatment focus: Soothing the nervous system, building secure connection with yourself and others.

How the field has changed

For a long time, partners of people with unwanted sexual behavior were treated as part of the problem. The label of co-addict or codependent was used to describe them. Treatment for betrayed partners was often handing them a list of flaws to fix.

That began to change when Barbara Steffens and Robyn Rennie published a 2006 study finding that most wives of sexual addicts responded to disclosure with significant trauma-related distress. Steffens's later work, and the founding of APSATS (the Association for Partners of Sex Addicts Trauma Specialists), moved the field toward treating partners as people who've been traumatized. Robert Weiss, in Prodependence, says codependency is an outdated pop-culture notion rather than a formal medical diagnosis. Weiss writes that instead of prescribing betrayed partners to form "detachment with love" or instead of treating the partner like an addict who needs their own intervention program, Prodependence validates their pain, honors their commitment, and talks about practical tools and healthy boundaries while staying relationally engaged.

The trauma lens was a huge step forward. Partners had their pain named correctly, but using a trauma framework alone tends to focus on symptoms, such as hypervigilance, intrusive thoughts, and sleeplessness. 

In recent years, partners and clinicians have noticed that something was left out: the relationship itself. Why do we want connection with the person who hurt us the worst? Why does this decision feel so loaded with pain and/orshame?

Attachment-focused work, including Mays', answers the gap. It treats the relational bond as central, not background. Mays has said that the more she studied attachment research, the more sense it made that so many couples stay together after betrayal. Her broader work also describes cycles of fear, shame, and powerlessness that keep betrayed partners from using the skills they've learned.

Where the treatment seems to be evolving is integrating the two. Trained clinicians in the field are using both maps. Trauma-informed care gives partners safety, stabilization, and validation. Attachment work helps with the relational pain trauma symptoms don’t fully capture. Betrayal trauma theory explains the fog and self-doubt, but not the need for attachment. 

What this means for you

Choose a therapist who knows more than one model and can explain which one they're using and why.

Some questions worth asking when you're looking for support:

  • Do you treat me as someone who has been traumatized? 

  • What are your thoughts about codependency?

  • How do you work with the pull between wanting closeness and wanting distance with my partner?

  • How do you help betrayed partners rebuild trust in themselves again?

Good answers will sound like a plan based on therapy models. Vague answers might feel like a map with parts missing.

And if you've been judging yourself for not seeing it, for staying, for leaving and going back, or for feeling two opposite needs at once, these models point in the same direction. Those reactions are what a human nervous system does when the person it trusts becomes the person it fears.
