Sounds like he may have some serious problems. I've been in a relationship for several years with a woman I won't marry and I don't give nearly the support she deserves. She thinks I just like my freedom...she's not aware that I'm emotionally crippled and incapable of a healthy relationship. I'm with her because she's busy and her willingness to keep a bit of distance suits me. If you haven't already, you may try getting him to open up...I mean, you probably already sat him down on the couch and tried to get him to talk about your relationship (ugh ) but I mean open up about what's bothering him about himself.
