Right, well I'm a IDVA and I can tell you you're way off the mark with how abuse manifests in the victim. I can't tell you how many clients call my service and start with the phrase 'I'm so sorry to waste your time, I'm not sure if this is abuse or not but...' and then go on to describe high risk behaviour, incredibly traumatic behaviour. It is insidious and many, many victims don't realise they're in an abusive situation, especially when they've been told that the abuser only said or did something because of the way the victim behaved.
Communication is not equal when it comes to the victim/abuser dynamic. You're not talking about two people trying to reach a resolution; you're talking about ONE person trying to reach a resolution and the other trying to win a battle the other person doesn't even know they're having. Conversations where the victim tries to tell the perpetrator that they don't like something they're doing immediately puts the perpetrator on the defensive and sounds like this: its your fault, you're the one with the problem, I wouldn't behave like that if if you hadn't done this, anyone normal wouldn't be bothered by what I've done, what about when you did that thing to me, and anyway you just misunderstood it in the first place.
Is it any wonder people go to a therapist to help them unpick it all? As a Clinical Psychologist, you might want to consider attachment theory alongside traumatic bonding and why exactly a victim may not immediately recognise the dynamic as being abusive. And please never, never suggest to a client that they confront their abuser with the idea that they are abusive, or suggest that they should just talk to them about it. There is a reason mediation between such couples is never recommended, and why psychologists running perpetrator programmes approach abusers so carefully and ONLY with safety planning firmly in place.
