This friend of mine has been flirting with me and I think she likes me but I don't like her like that..help?

You could try putting her into the friend zone by saying "hey ya know your a really good friend" emphasize also you could tell her about the girl you like maybe if she hears your into someone she could help she'd also totally get the hint i'm sure she just likes how nice you are to her but if you get a girlfriend she'll still like you and you could also ask her if she's into you like that and just tell her your not into her like that...
