Recently, I messaged a "friend" of mine via facebook/myspace. By, "friend", I mean she's a mutual friend of mine between myself and my friends who I hang with. We've talked.. maybe 3 times, she's never really around when I'm around. I had a fling with a good (I don't know if they're still THAT close) friend of hers which kinda blew up in my face when she found out I was having a fling with someone else. Still following me? Hahaha
When that blew up in my face, a lot of the girl friends that hang with my group of chums have this secret hatred for me. They never express it, but I know they talk behind my back and are still upset. Big deal.
Anyway, I messaged my mutual friend asking how her summer has been, and it seems to be hitting off pretty well. Lengthily messages, her asking a ton of questions about me and the band I play in, and ending with "it's really good to hear from you

". Obviously, I'm in the right direction.
Anyway, should I still keep up with this? I want to, not quite sure what I want out of it... a relationship would be very nice, casual sex would be even better. But I feel like she might mention me to the group of girls that HATE me, and yet again, this could blow up on me. Thoughts?
