First of all, if the house is in only your name, it is not up to him to say you can or can not sell it. The house is yours and it is your decision not his. Second, I would start the divorce proceedings (maybe there are lawyers who do probono work or discount work for low income families where you are) and once you have some papers in your hand you can call the police and make then get him out. I think you are right and your future is without him. However, only you can take the first step and then follow through on it.
