I could give you a long, involved list of reasons he has issues, like many of the people on this very site. In an interest of brevity, I gave a few quick all-encompassing themes to give an idea of what kind of social issues he faces. I'm really not trying to defend him or make excuses for his behavior but he is messed up much like I am messed up and I think that is part of the reason I am so attached to him.
He makes me feel not so crazy and fragile. He is incredibly smart, funny, sexy, and can be sweet when he wants to be. However, he doesn't give me the emotional exchange that I feel I deserve. I definitely put more into the relationship than he does. He has even acknowledged it. The thing is, it isn't the unavailability, the stoicism, the great sex, the unpredictability that draws me to it. It truly is his personality and his potential. I just feel like they are both held captive by his fears and neuroses.
Everyone else I've dated, I just imagine them talking to him and they can't hold a candle to him in wit or humor.
I'm just miserable waiting around for him to be available or get over his paranoia. But I can't imagine being with anyone else..
