what happens when you THOUGHT you didnt like someone, but when you find out who they like, it feels like a blow to the stomach?

Thats what happened to me.
In jazz band, theres 2 basissts (i dont know why)
me and the other dude.
everyone thought the other dude liked me
(But i guess not, huh?)
Well, I didnt like him (so I thought)
today on myspace, he said:

the certain some1 i like likes me i think. im not sure

and I said: who do you like??

He told me to do the locker thingy on his myspace. I did. He likes one of my firends, and amanda said that girl likes him too.

When I found that out, it just hit me hard. really hard. Now im really sad..

What do I do??
