So there is this on girl in my grade (11 people by the way) and I have known her for a year and a half but I really like her and recently I have became pretty good friends with her and my friends know I like her and At lunch we were talking about crushes and she was at my table and she said she liked no one and then my friend said that she likes me and she got all red I was going to ask this other girl in my class who is also my friend and the girls friend if she knows if the girl I like likes me but then I'm worried that she likes me because she is always trying to say to me and stuff so I'm worried that if I ask the girl I like if she likes me and I get turned down then my friends will tease me but it's like a game of chicken because I don't know if she really likes me or not

Honestly just go for it. If she say yes good, if she says no fine. If you get a no it shouldn't too hard, especially with such a small group, no more than a few jokes will be made about it and those wont last that long.

I agree with Azael. Besides, by what you said it seems she could like you as well so you should ask her. If she sais no, you'll be able to move on which is a good thing. If you do nothing, the thought will never leave your mind and there's no need for that. And i don't think you should be worried about your friends teasing you, they'll get over it eventualy:)
