text: if she has liked you before...she at least somewhat likes you now too.  One idea you could try, is talk to her and tell her you can help her get the guy to ask her out (the one she stares at).  She will probably be happy that you are helping her and will talk to you a lot more.  Ask the guy who he likes and try to hook him up with another girl.  THen when the girl you like is upset from this, you will be there for her.  She will start to like you again because you will become closer and she will see that she can trust you.  IF you feel guilty about doing this though, you can follow through and tell her what you did and say you were so sorry you didnt mean to hurt her but you just liked her so much and would do anything for her.  I dont really have any other advice, but you can also get some friend girls to ask her who she likes and whats going on.  good luck!!!!!!!!!!!!!!!! xo
