Abuse extends far beyond what someone says to you or how they behave toward you. It embeds itself in what you eventually begin to say to yourself, and it often remains long after the relationship has ended. Throughout the relationship, the abuser works to replace your own thinking with theirs, until their judgements and your self-perception become difficult to distinguish. Many survivors only recognise this once they have left, when the criticism continues but there is no longer anyone there to deliver it except themselves.
It starts during the relationship, at a time when you are still trying to understand what is happening around you, and it develops in a way that is gradual enough to be difficult to identify. By the time many survivors leave, the abuser has already laid the groundwork. The internal framework they created does not disappear when the relationship ends.
How the abuser works their way into your thinking
At the start of the relationship, you rely on your own perspective. When something feels off, you speak up, expecting that your view will matter. The abuser does not respond in the same way. They push against your interpretation, introduce their own version of events, and continue presenting it as the more reasonable account until your sense of certainty begins to shift.
They pay close attention when you explain your thoughts and emotions, then use that insight to interfere with how you process things. They question your reactions and suggest that you misunderstood, and they repeat this dynamic until your trust in your own judgement begins to erode.
This process is described in depth by Don Hennessey, an Irish counsellor and researcher who has spent more than 40 years working in the area of domestic abuse. As Director of the Ireland National Domestic Violence Intervention Agency, he has worked directly with hundreds of women and more than 1,000 male abusers. In his book How He Gets in Her Head: The Mind of the Male Intimate Abuser, Hennessey outlines how the abuser gradually replaces the person’s understanding of events with their own interpretation.
He writes that the abuser “gets inside her thought process and replaces it with his worldview,” altering how she interprets what is happening and how she understands her own responses.
His work centres on male abusers and female victims, but the psychological mechanism he describes applies across different dynamics. Abusers establish control by reshaping how the other person thinks, not only by directing what they do.
When their voice begins to take over
Challenging your perception is only the starting point. What the abuser is ultimately aiming for is to get you to carry out that process yourself, so that you begin questioning your own thinking before you even speak.
This is how the shift unfolds. You start anticipating their reaction to what you are about to say, and you adjust your words accordingly. Then you begin adjusting your thoughts before they even become words. The abuser pays attention to this change. When you begin to use their explanations and their language, they recognise that their influence has taken hold.
Hennessey describes this stage clearly. He explains that the abuser “gets his voice into her head and monitors it when she begins to speak with it,” illustrating how control moves from something imposed externally to something that operates within your own mind.
When their criticism becomes your self-view
Once that voice is established internally, the next stage is what it does to your sense of self. The abuser has spent the relationship positioning you as the problem, framing your reactions as unreasonable and their behaviour as justified, and repeating that narrative often enough that you begin to accept it. You stop waiting for them to criticise you. You begin doing it yourself.
At this point, the abuser no longer needs to defend their behaviour, because you have taken on that role. You look for explanations that place responsibility on yourself, and those explanations start to feel more accurate than any other way of understanding the situation.
One survivor described how this process took hold:
“I used to think it was my fault. That maybe when he told me I was grandiose that he was right. That I needed to communicate better.”
Hennessey explains that the abuser recognises this as progress, when the person begins “using his explanations and his language to minimise or ignore the effects of his behaviour.” At that stage, their perspective has been fully internalised.
Another survivor described how complete that internalisation can become:
“Often, she was merely echoing the worst things I used to say to myself. I could not usually offer any counter-argument because I already believed these things, that I was a failure, that being with me was a burden, that she could easily find someone better.”
One survivor explained how this internal voice continues long after leaving:
“We completely rely on them too. Put all our trust in them assuming they know best, while we make ourselves smaller, constantly wondering what is wrong with us. I became a mess because the real me kept fighting from deep within. At least now he’s just a ‘weaker’ voice in my head.”
Another described the same experience years later:
“The constant, low-level criticism is still a voice in my head, six years later. It sticks because he continued where my mother left off.”
This is how internalisation settles in. The criticism continues without the abuser needing to say anything.
How you begin to regulate yourself
Once the abuser’s voice is operating internally, it starts to shape your behaviour. You run decisions through what they would think before you have even made them. You anticipate their reaction and adjust accordingly, not because they are present, but because the pattern has become so established that your mind continues to follow it automatically.
Hennessey describes how each thought begins to pass through this internal check, with the person asking themselves what the abuser would think before acting. What began as a way of managing the relationship becomes a default way of functioning that continues long after it has ended.
Survivors often recognise this most clearly in everyday moments. One survivor described how these rules remained in place even when there was no one left to enforce them:
“I only knew who I was with him. I could do whatever I wanted, but still abided by his rules even when I didn’t have to. I still revert to this whenever I am emotionally vulnerable.”
Another described how this appears in ordinary behaviours, even decades later:
“It’s been 20 years since I got out, and I still find myself folding the chip bags his way, and driving his way.”
These details highlight something important. The behaviours that once reduced conflict became so ingrained that they no longer felt like adaptations. They started to feel like the natural way of doing things. This shows how deeply the abuser’s expectations can take hold.
Why it carries on after the relationship ends
Many survivors describe a specific kind of disorientation. The relationship is over, the person is gone, and yet the internal experience continues as though nothing has changed. The doubt remains. The hesitation before decisions remains. The sense that criticism is coming, even when it is not, remains.
This is confusing because there is nothing external to point to. The abuser altered how you think, replacing your internal reference point with theirs, and that structure does not dissolve simply because they are no longer present.
Hennessey describes this as a form of psychological invasion, where the person loses the ability to trust their own thoughts and begins relying on the abuser’s perspective instead, a perspective that continues operating long after the relationship has ended.
Reclaiming your own voice
Recovery begins with recognising that this internal voice was learned. You start to notice the patterns, the doubt that appears when you begin to trust yourself, the criticism that follows a decision that felt right to you. These thoughts follow the same logic the abuser used, and recognising that is what begins to weaken their hold.
That awareness creates distance. You begin to see that these thoughts were shaped by someone else’s influence, even though they now feel like your own. You start to examine them against your own understanding of what is true, your own values, your own experience, instead of filtering them through the abuser’s perspective. Their voice may still appear, but you begin to recognise it rather than accept it, and as that recognition grows, your own voice becomes clearer.
Hennessey describes what becomes possible when this process begins. “She can gradually restore her ability to examine these thoughts and ideas against her own criteria and value system. She can allow the voice of her instincts, quietened for so long by her abuser, to be heard again inside her head.”
For many survivors, that is exactly how it feels, a gradual return to yourself, one small moment at a time.
