I am so sorry for your situation.  It can not be easy for you but You sound like you are a string person despite your situation.  You do not need an attorney to file for divorce.  But they can help to fight for your rights, which is what you need here.  What you need is to file and ask the court for exclusive occupancy of the home as well as a restraining order against him given the situation.  That will help to resolve the situation for the time being.  Good luck.
