Sorry to hear about your troubles, it certainly sounds like you are going through a very difficult time right now.
The easiest solution to your problem would be to ask him to leave and see if he will comply. Once he has moved out of the residence you can legally change the locks and refuse him reentry to the residence.
If he refuses to leave the residence you can initiate an action for a Divorce from Bed and Board. In this action you ask the court to order your spouse to leave the residence. Based on his behavior you may be able to get a divorce from bed and board. However, litigation is an expensive process. If he refuses to leave on his own I would consult with an attorney and have them make a formal request, before initiating any legal action. Good Luck.
