I'm sorry that you are going through this.
Verbal and emotional abuse are never okay.
I would recommend couseling for the two of you and also for you by yourself. It helped me alot learn better ways to respond and not respond to the verbal abuse. I learned how to take back my power and not let him manipulate me.
If you don't think it'll get better, then I recommend consulting with an attorney. I waited too long, but I finally got out and am so happy living in peace and quiet.
My ex- finally went for the help and medication that he needed and now we get along much better, but I still don't have to live with him! :)
