I think you made the right choice. It must have been incredibly hard to make. You had put a lot into that relationship.
As far as what he's feeling....... I think there's a pretty good chance he can't admit what he actually feels, even to himself, much less to someone else. I hope, at some point, for his own good. he takes the time to honestly look at his behavior and consider whether that's the way he really wants to live the rest of his life, and then decides to work on getting his act together better. For you, I hope you find the relationship you deserve, because what you deserve is pretty awesome. :hug:
