Man, Dazed, I know what you mean. I was dating two guys during the same time(by dating I mean, as casually as you could use the word. We went on dates, we hung out, we made out. They all knew about each other, and everybody was fine with it, we were all doing the same thing.), and I kind of developed feelings for both of them. I told each of them, and was rejected by both. One wasn't ready for a relationship, and the other didn't feel the same way about me. I was fine with it, I mean, given the circumstances, it was completely understandable, and I had no reason to really be upset. It was hard for awhile, but I got used to it.
One of the guys sort of faded away, and we don't talk so much anymore. The other guy is one of my best friends. He is like a big brother to me now. He recently started dating(seriously) this lady, and I wish him the best. Seriously, dude is a cool guy.
But yeah, I will second the advice and say date around. Don't sleep around, but go out on dates with people.
Also, Blarg thread,
They turned the water back on! I peed and brushed me teeth! I feel cleaner!
