Hi OP,
So sorry you are going experiencing such pain.
No point in telling an abusive man he is abusive. I went through this too and for a time thought that 'if he only knew' how upset he made me, then he would stop.
This does not happen. Of course he is fine when things are going well. He only brings out the big guns when you dare to stand up to him. You are not allowed to disagree with him. You are not allowed to stand up to him or express an opinion different to his. That is when he signals that you will be punished. Or just punishes without signal.
Yes, you are being punished for stepping out of line. This is his method for getting everything his way. His way does not include you being happy. He does not care about your happiness if it gets in the way of his. Ruthless isn't it?
Non-engagement is a temporary measure. It's like wearing a tin-hat - ok for crisis moments, but you don't want to have to wear one for the rest of your life and it is no recipe for an actual relationship.
He doesn't want you to 'hold your own' in the relationship. He wants you to put up and shut up, and the threat that he will punish you emotionally is always there.
The question you need to answer for yourself is 'What kind of bastard would heartlessly seek to undermine the emotional wellbeing of the person he is supposed to love most in the world? What kind of person does this?
You know what he is doing - minimising, dismissing you, ridiculing you - all punishments. There is a constant threat level with something like this: he is not doing it all the time, but the threat is there. He doesn't have to be like this all the time - mostly all you need is the threat to keep you in line.
This is probably not the person you want to be. I have been there. It is a shock to realise the the person you love is more prepared to see you unhappy than to change their behaviour or compromise. 'How can someone who loves me do this?' you ask yourself, and in the end I realised that someone who loves their partner does NOT do this.
I had a husband that I thought - underneath his angry or grumpy exterior - was essentially a decent and kind man. The fact that he was terrorising me emotionally meant that my firmly held belief could not be true. These were two mutually exclusive concepts. Once you've excluded all the other options, what's left, no matter how unlikely, must be true.
