He says that he wants to change. That he's tired of being angry all the time and hates himself for hurting everyone closest to him but doesn't know how to control himself. There's been times he's even cried with his head in my lap begging for me to help him. So I try even harder to be there for him but then i get discouraged when he does certain things because a part of me wonders that he says that to me in order to keep me there, but another part of me thinks that if he's being genuine about wanting my help and I walk away then i'm abandoning him in a time of need. I'm torn.
