confusing virgo girl?

Theres this girl i like. I thought she liked me back she would always stare at me and stuff and her friends talk to me and stuff. Whenever her and her one friend are together her friend always looks back ad smiles. her friend even pushed her into me one time as a joke and they were both laughing... But last night was confusing. I was going to get my friend to tell her i liked her and right as she said my friend, she said im straight. She doesnt know my friend. So how did she know what she was gonna say. So ever since that happened her friends started waving at me and whenever me and my friends would meet them somewhere they would run away. Then start all over. And i just started talking to her friend tonight. And her twitter says (my crushes name) is inlove. She says its with her brother. But she made that tweet right when all this stuff was happening. Oh and also as i was talking tobher friend she was asking what qualitites i like about uer and she said if i try really hard i may change her. You cant just changem everyone knows that. So im thinking this girl likes me and her friend is just keeping her secret at the same timentrying to get me to try harder for her. I will try harder if she likes me. What do you think is going on.?

To me it looks like her and her friends picked up on your crush for her and are teasing her about it. I think you should back off and stop giving her and her friends attention and see if she makes any contact with you on her own.
