Do I have a right to feel the way I do?

Nah, if you're stupid enough to stay in that relationship, do you really think you have many rights? If you choose to stay with him, you choose to accept what he is. No matter what he says and if he gets help and if he promises, he will never change. he is who he is. You've been getting hurt, physically and emotionally. You are getting hurt and will continue to get hurt if you don't leave. How dare he yell out that you have HIV. That is personal. It would be A LITTLE different if it slipped out when he was talking to one of his friends but yelling means he was angry and he disrespects you and will continue to do so until you respect yourself and leave. I hope all the best for you.
