I went to an attorney because I wanted my xah to leave too, and he refused. Divorce wasn't even my primary goal at that time. In the state I live in, they could grant me temporary use of the marital home (and as Jayscott said - custody/child support) - and he would have to leave, escorted by the police if that is the way he wanted it. That was part of filing for a divorce. I could have stopped the divorce at any time if I wanted to but that would have gotten him out.
I hope your attorney has some answers for you tomorrow.
