Kicking someone out

I am trying to be proactive and think about what will happen if I truly decide to end things. Dh and I both have our name on the mortgage. I started back to work a month or two ago and can pay the bills, but not anything extra for an apartment. Also, me leaving with the kids would leave him the house that I do not trust him paying for. Therefore, he would screw up my credit. I don't think I can refinance on my own b/c we have too much credit card debt and I don't make enough. If he refuses to leave, is there anything else I can do to make him leave? He does not have a regular job and cannot afford the mortgage without my paycheck. I do not have family nearby that I can stay with.
