@Soscared29 my first message about your behaviour had been before you’d described what your behaviour was, please read my second post. You were absolutely not abusive, and in no way encouraged a response so aggressive from him.
You still struggle with it because you were abused. He wasn’t, he was the one doing the abusing which is why he can walk away unaffected. Every couple has arguments, arguing is not being abusive towards him. His response to you arguing back was though.
You’re probably still stuck there for the same reason thousands of women stay and mourn the loss of their abusive partners, you can’t make sense of what happened and you feel like it was you that was the problem. If only you’d been good enough, happy enough, agreeable enough. If only you’d been able to be exactly what he wanted you to be, then none of the abuse would have happened. You feel responsible, you feel that you weren’t enough and you’ve not been able to get closure for it.
It’s an incredibly long journey to closure and healing from what you’ve experienced, but it’s well worth making it. You’re trying to make sense of a situation you had no control over, that’ll never happen but you will eventually be able to move on with the right help and support.
At least that’s what they tell me. I’m trying to start that journey myself, not quite ready to get though. But you are away from your abuser and that is the first step, I really hope you are ok and manage to work through this
