The answer is, at least for my situation. He is afraid that I am bad for him. He told me he sees qualities in me that he sees in the addicts at the rehab center. He tells me its too hard to talk to me everyday. I know he is confused and loves me and he is afraid to keep in touch with me because he doesn't want to lose sight of his mission which is getting clean. So I will walk away to help him but most of all I'm doing it for me . :-)
