Why Does He Do That? Bancroft on Values, Control, and Relationship Patterns

What Bancroft Actually Explains About Control and Values

Lundy Bancroft's "Why Does He Do That?" is not a book about psychology. It is a book about values. Bancroft spent decades working with men who abused their partners, and he observed something that clinical attachment models often miss: the behavior is often deliberate. The man who monitors your phone, isolates you from friends, or erupts when you spend money is not always acting from fear or insecurity. He is often acting from a conviction that he should control you, paired with the discovery that he can. That is a different problem than attachment anxiety. It requires a different response.

The reason many people get stuck on this question is that they keep looking for the wound. They believe if they understand why he does it, they can fix it by being what he needs. But Bancroft's central insight is that controlling behavior, particularly when it escalates, is often about entitlement and choice. A man can be terrified of abandonment and also choose to isolate his partner. Attachment anxiety does not cause control. But an insecure attachment style combined with a belief system that justifies dominance, paired with the absence of consequences, often produces it. Those are separate things. You need to know the difference because it changes what you do next.

Attachment Anxiety Is Not the Same as Control

John Bowlby's original attachment theory, developed in the 1950s and 1970s, proposed that human beings are wired to seek proximity to a trusted figure, especially under threat. When that figure is reliably responsive, the child develops secure attachment. When the attachment figure is inconsistent or unavailable, the child learns to heighten their signals for connection, scanning constantly for signs of withdrawal. This hypervigilance persists into adulthood. Levine and Heller call this attachment anxiety in their model, and it shows up as the need for reassurance, the checking of your phone for a text, the asking where he was and with whom.

Attachment anxiety feels like panic. It feels like you cannot relax until you know he is not leaving. You interpret his silence as rejection. You read distance in his words. The anxiously attached person is often the one doing the monitoring, the pursuing, the adjusting. But here is the critical part: they are not trying to control him. They are trying to make contact. They are trying to get proof of his presence.

Control is different. Control is when he monitors you. Control is when he tells you who you can see and what you can spend. Control is when he has decided what is acceptable, and he enforces it. Someone with attachment anxiety might cling. Someone with a controlling pattern isolates. Someone anxious asks "where were you." Someone controlling says "you should not have gone there." That difference is not subtle. It determines whether talking about your feelings will help, or whether it will be used as more material for scrutiny.

When Insecurity Becomes Justification

Bancroft's observation was that many of the men he worked with had insecure attachment patterns. But insecurity alone does not explain the behavior. What explained it was the combination of insecure attachment, a belief system that positioned control as normal or deserved, and the discovery that the behavior worked. He got what he wanted by monitoring her phone. She stopped going out as much once he made it clear he disapproved. He stayed because she stayed. The system reinforced itself.

This is where attachment theory gets dangerous when it is applied too broadly to explain controlling relationships. If you tell yourself that he is anxiously attached and that is why he monitors you, you have imported a framework that makes his behavior seem like an attachment problem that might be solvable with more closeness, more reassurance, or more understanding. It is not. Bancroft spent his career watching people try exactly that approach with men who had no intention of changing. The closeness became access. The reassurance became more information to use in control. Understanding became a tool for him to refine his justifications.

That does not mean attachment anxiety is not real. It means that attachment anxiety explains a lot of relationship distress but not a lot of relationship abuse. Someone with anxious attachment might be clingy and afraid of abandonment. But they are not usually the one controlling access. They are not usually the one who escalates to violence when boundaries are pushed. Bancroft's point is that when you see that pattern, you are looking at something else: someone who has decided that control works, and does not care much what you want.

Recognizing the Difference in Your Own Situation

This matters because your response has to match what is actually happening. If you are in a relationship with someone who is anxiously attached but not controlling, the standard advice about secure attachment applies: consistency, boundaries, reassurance that you are present but not consumed. If you are in a relationship where control is the actual pattern, that same consistency will be interpreted as proof that he can push further. Boundaries will be breaked. Reassurance will be collected as leverage.

Bancroft suggests a practical test: watch what happens when you say no. Not in anger, but clearly. You are not going to do this thing. You are going to spend time with your friend. You are going to make this decision. Watch whether he responds with hurt, fear, and increased pursuit of connection (attachment anxiety), or whether he responds with anger, withdrawal of affection, isolation, threats, or blame. The anxious response opens a door to conversation. The controlling response closes every door in the house.

Watch also whether the behavior is responsive or imposed. Someone with attachment anxiety is reacting to perceived threat. He becomes anxious when you are distant, withdrawn, or absent. Someone with a controlling pattern often initiates the behavior regardless of your closeness. He tells you what to wear even when you are home together. He checks your phone even when you have done nothing that warranted it. He creates the surveillance system, not in response to a security threat, but as a matter of principle.

The pattern keeps running because it has never been named for what it is. You have been looking for the wound that explains it, when the actual problem is the choice to inflict one. Recognizing that choice is not the same as blaming him. It is the same as taking your own clarity seriously.

If you want to understand your own attachment patterns and how they show up in your relationships, the My Values relationship values assessment will map where your values actually sit and where you are living them or not. That clarity is the foundation for any decision that follows.
