Good for you! You are not to blame in any way. I would like to see you go to court weds and stand up for yourself. He brought these things on himself and if you back down the cycle will get faster and a lot worse (ending many times in death).Take care of you and yours and let him deal with his own problems.
Sounds like it was a pretty bad scene and I'm sorry you had to go through that, make last time THE last time!
