Then it sounds like you have to force the issue. Ask him to go to MC with you.
If he doesn't, then tell him you're going to file for divorce.
He's holding onto the only power he has over you -- the fear that you won't kick him out. Take that away from him and see what happens.
But you can't bluff. If you tell him you're going to file, you have to be ready to follow through. If he senses you're bluffing, you won't have a leg to stand on.
