does she want to be my friend or just teasing me

hi, the girl i liked is acting very weird ever since i told her i liked her...when i told her she took it well and for like a week she was nice to me and would always smile whenever we looked at eachother...but then she started to completely ignore me and flirt with other guys in front of me...so i thought this was her way of telling me she liked me. so now she got her blackberry messenger back..her parents had taken it away...and she came up to me...do you still have me..add me...so i did...does she want to be friends now because she had changed her number and hadnt given it to me...so i guess she didnt want to have anything to do with me...she also started using me a lot in her work...she stopped calling me by the nickname she gave me unless she needed help in something...so yah...WHAT THE HELL IS GOING ON!!!!

we're both 15 year old freshmen

She had beeen giving me signs before but then stopped

She still likes you, don't freak out about it. She doesn't want to appear clingy. I think she wants more attention from you. Good luck

Hope this helps.

Can you help me with my question please? Thank you ;D
