I agree with JT. Men who say such things aren't interested in commitment, and are placing the blame for the relationship's eventual demise at your feet. After all, he warned you...right?

It means he wants to use you for sex and companionship (on demand and only when convenient) without you expecting any kind of long term commitment. Move on immediately.

Sometimes, some people that we meet in our lives can be so full of potential in terms of what we are looking for in a relationship, yet they, at that moment, are "broken", if you will.

He is telling you not to love him for many possible reasons, and its up to him if he is going to share any of them with you. I dated a woman once who told me the same thing. She had a lot of baggage - serious childhood issues with her parents (and I mean uber serious), abusive relationships, all of which led into self-esteem issues and eventual drug usage to help her try to maintain some sort of equilibrium. She knew that eventually she would do something to hurt me. Not on purpose, at least not in any controlled sense, but she knew that since I was the "nice guy" that she eventually wouldn't know how to be with me because it was so far out of her realm of understanding...most of her exes were a-holes who only fed her more abuse that she understood and was used to. Doesn't mean she liked it, but she didn't know how to get out of it and wasn't ready to when I met her.

Your guy may have some serious issues, and he knows he is damaged goods right now. You won't be able to save him, and the only way you'll be able to help him is if he is actually ready for help and asks for it. Otherwise, he knows that he will hurt you eventually, but he is to selfish right now to just outright not see you at all to keep you safe from that. He may, eventually, finally find the strength to change his life around, but it won't be because of you. I'm not trying to be mean with that, but it is the truth. We can't change anyone but ourselves, and if he isn't ready to change then there is nothing you will be able to do about it.

My ex, by the way, has changed her life around. Its been 10 years since I first met her at the strip club she was working in. She now is back in school, married, and has a beautiful baby boy that means everything to her. When I knew her there wasn't a religious bone in her body...now she is a regular church goer and participates in the church's organized events. It took a lot of cathartic moments for her to finally find a reason to change, and her getting pregnant, but she is unbelievable happy now.

So, its possible that your guy can change...but I really wouldn't hold my breath right now. He will change when he is finally ready to deal with his demons.
