You aren't married to him, you pay the bills and you own a house together. You need to copy all of the documents that prove you are paying everything. Also document, date, time, sign and state all of his abuses in one notebook, hidden from him. Find a different attorney. The Judge will see who is truthful and who isn't. Somehow, you will need to get his name or yours off of the deed to the house....
I feel for you. A controlling person is really out of control. That behavior progresses in my experience. I really hope you find a better attorney, try to file that restraining order and somehow get him out of your life. He needs help and as long as he is feeling that he has control, it's going to be difficult. Those babies need a stable environment to live in.
I don't know enough, but please find out how to get out of this situation. My opinion.
I wish you well, whatever you choose.
Peace, love & hugs,
