I have Aspergers, and apparently that scares guys off. Every guy I've ever cared for had rejected me in a rather painful manner. There's a guy I like right now, but he'll only reject me, too. Just like all the others.
Its pointless for me to have those feeling for anyone, as I will only get hurt every time. They'll tell me in subtle hints that I'm not good enough, that I'm creepy, and that I'm weird. They'll tell me the reasons they wouldn't be good for me, which I've learned is only masking a more direct statement:
"I'm not interested in you. I don't want you. You're not good enough. Stop liking me."
Yes I'm bitter. Yes I'm afraid to have feelings for anyone. I'm so sick of being rejected and hurt. Nobody can love me. It also doesn't help that I'm fat and ugly. No guys want girls like me. I'm fat, ugly, and I refuse to conform to society's image of 'feminine'.
