Does He Love Me

The porn issue is a hard one for me, no pun intended. I don't know if he'll do it or not, but I'm assuming he will. That is hurtful, since he hasn't been interested in sex with me. At the same time, it sort of seals the deal for me. I don't really want to tell him this. I feel like any time I want to tell him something openly about the leaving process, he takes it as manipulation. I can understand that. It is like I am holding my leaving over his head. Nothing in his behavour has changed. He isn't really interested in fighting for me, but is taking this opportunity to fight with me. I just wish I knew whether he loves me. He says he does, but really, he does not treat me as he once did, not at all. He does not seem to enjoy my company, or even my presence. We do not talk like we used to. We hardly talk at all.  I think if he told me that he didn't love me, it would be much simpler. But this half hearted insistence that he does love me with no action behind it, is it worth devoting my life to?
