Why do I bother?

A guy who I haven't heard from in weeks showed up at Bound last night, telling me all the reasons he hasn't contacted me. He said that he came out because he thought I might be there. If that's true, it's one of the nicest things anyone has ever done for me. But I have a difficult time believing him. So many people have lied to me throughout my life, especially men, that I have to have a healthy dose of doubt about anything they say. And he says he can't be in a relationship right now. I want to believe him, because I like him and had a good feeling about him, but my history with men, and the other girl I saw him with last night, give me a bad feeling. One of my problems is, I assume that anytime someone says they can't talk to me or see me, it must be my fault. I assume that everyone I meet will hate me, because they'll somehow manage to read my mind and see my various insanities. It's not the best way to live, I know, but I can't help it, not even after years of situating myself in the social sphere, and therapy. I hope this guy's telling the truth, even just to give me a shred of faith in humanity and my future chances of a happy relationship.
