Youve already identified the answer. Be there for him and be his friend. Thats what we do for the people we love. Ive never understood how a man can go from one relationship to the next. I guess its just the way men are wired. They all do it, so try not to beat yourself up too much. Its him, not you. Woman are wired to be emotional and men are not which is why he probably gets so angry when you push him. I have bipolar disorder and what youre describing is the very reason I dont date or seek a serious relationship. Its too hard to cover up the illness, and the illness is impossible to control. Hes lucky to have found someone like you who is willing to love him unconditionally, but you will have trouble. Hugs and kisses sweetie!!
