need help

HI everyone.. I need some relationship advice. I ahve been with this guy for 6 months. We both had some big issues coming in.. I was trying to get a divroce and his ex was maybe pregnant with his kid.. We do fight a lot mostly because I have a trust issue. Lately he has been very distant. He works in a very high stress work place and just found out the child wasn't his. He hasn't been affectionate, or wanted to be intimate. He barely raises an eyebrow to me. He says he loves me but don't know what he wants. He tells me if I want to leave then leave. I am not sure what to do anymore. He is pushing me away but he says he is not. We live together and he helps raise my son. I know he has a lot of stress on him and he holds everything inside. I am just really hurting and am not sure what to do. He says he loves me, don't know what he wants, but then dont want to be physical or intimate, I think there is more wrong.. Any advice please? Tweet
