OP - when the big confrontation about his abuse occurs...the one where you have reached the point of finally putting him out...he may well start to attribute his dreadful behaviour to various things.
He may say that you drive him to it. He may say that you are selfish or unloving, or that you wind him up, so therefore, you bring it upon yourself. You don't, and this angle is designed to make his behaviour seem justifiable and even reasonable. It isn't.
He may say he is stressed. Maybe at work, or with the demands of being a father. Maybe because of lack of money. He may behave as though he is ashamed of his anger, but can't help it because he is so stressed. Remember this - he is not abusive because he is angry...he behaves with anger because he is abusive. Make the distinction and be firm on it.
He may say that he has felt shoved out because of your dd. This is a common tactic of abusive men. There is no doubt we love our children more than anything, and abusive men exploit that as a stick to beat their spouses with. It is an effective way of making their wives prioritise their own wishes above all else, while leaving plenty of leverage for guilt mongering should their spouses step out of line.
My point is, there are many things he may say to explain away, and justify his rotten behaviour. He will be convincing too.
Unless he is able to admit he is abusive, and personally take firm and decisive action to seek the appropriate therapy to stop his abuse dead, then he is an absolute dud.
People like him behave the way they do because one way or another, they think they're entitled to and it's ok.
Normal, healthy people do not behave this way, because they know it's not, and there's no pleasure to be found in being a cunt.
All the very best to you. xxx
