I agree with a lot of, if not most of what Rose has said here. His problem has nothing to do with your worthiness either. He is showing you that he has not changed, and I honestly don't think he ever will either. You are still young yet, can find someone else that actually "can" be there for you in a healthier way. I don't feel sorry for him, I feel sorry for you in that you have been challenged with this kind of person.
