I have a friend who is a guy and my boyfriend is so mad about it.?

He keeps putting so much pressure on me, I would never cheat loyalty is an up most important thing to me. He just keeps throwing it in my face, we have a son and I have Multiple Sclerosis. I am to sick to think about anything. He keeps getting mad at stupid things, they fact that he has to clean things. Or he has to do stuff and he complains to everyone about it. He never talks he feels like he's above me. We are in a interracial relationship.. He makes me feel so bad. I don't know what to do..
