I'm so sorry for what you are going through. It saddens me that you are being treated that way. I believe you, too, should protect yourself. I have been married for almost 29 years, and my situation is quite different. Still, the lack of respect for you from him is very apparent, leading me to believe that he can't be trusted, and therefore you must take the proper precautions and protect yourself.
I would also get yourself a counselor if you don't have a good support system in place. There are options to help with the anxiety so you can begin to function normally. Maybe make an appointment with your primary care provider and let them know what's going on. You can get medication to help with the situational anxiety or get something to help you long-term. I tell you all of that because I am dealing with the same things and have lost ~20lbs in the past month. My thoughts are with you.
