I agree with both of my learned colleagues.
I'm probably out of line, but having seen my mother go through several abusive relationships, I can only say that I don't think he's going to change.
My advice, which you can choose to act upon or not, is to get the hell out of there. The abuse is only likely to worsen and whilst you are probably hoping against all hope that he will come round, change or whatever, I don't think this will happen and if it does, the dynamics of the whole relationship will have changed too and you are never going to truly trust him again.
It will hurt for a while, but I hope you will find it cathartic, freeing and liberating too.
It's just my opinion and I apologise if I really am out of line here.
