Crush?

So I label myself as Bisexual but honestly I don't know. All I really know is im queer. I've liked girls and guy so I assume I'm bi? And theres this girl who is in my grade. She's super swet and pretty. I liked her for about a year but now I'm unsure if i still have feelings for her. I mean sometimes when listening to music I'll make fantasies about her tellng me she likes me and we get together (especially when listening to "seven minutes in heaven" by Mindless Self Indulgence. Sometimes I think "oh I still like her!" and other times I think I don't anymore. I don't know whats going on with my feelings. And she doesn't even like me back. She's rejected me twice and I'm trying to push away my feelings. But theres this boy who is the kid of my parents friends. He's a couple years older then me and I just realized I might like him but again I'm not sure. Yeah, I get nervous when talking to him but I get that way talking to all boys. We just did a big group camping trip with his family, mine and others and he was tlking about how he made out with a girl the same age as me. Honestly it made me jealous for some reason. I even fantasize about him and I getting together too. Oh and my bestfriend who I've know from birth I think still likes him also. So I'm completely lost on this situation and dont know what to do about maybe crushing on two people. Everytime I think of them two I get butterfly's. I'm so confused with my crush, sexuality and I'm even questioning beng okay with being queer...
