Greetings. It sounds like you need a domestic violence restraining order which allows you to restrain him from entering the home and mandates that he must stay away from you and your son. It will not be an easy step for you to take, but if you talk to an attorney they can help you file the documents and go with you. After you get the initial order, the Sheriff serves him with papers and he cannot come home or he will be arrested on the spot. Best of luck.
