Ok I like this girl and I think she likes me but ?

Ok I`m in the 11th grade and she in the 12th grade were about a few weeks from gettin out of school, so in feb of 2010 I saw this girl walk in the lunch room I said o I like this girl so less known that she fin too sit 2 seats from me with her friends and i was seating by mines. So one of my friend told her that I liked her by me been shy faced I turned my head, but they told me that she started smiling. My friends told me that a good thing because she started smiling and she just broke up with her boyfriend a few weeks ago and the following day she was checking me out down the hall way and I was staring at her too. Ok the next school day which was thursday she sat next to me when i was talking to my friends I said o lord in my mind in I felt erflies in me .So do yall believe i didn`t say nothing too her in she was sitting next to me when she walk in with her friends, but she still didn`t give up she stop in smile at me and I smile in kept walking. But i still be seeing her looking at her ex boyfriend too so I`m confuse about that too I think she like kind of but she still in love with her ex cuz she still be watching him too I be catching her looking at him sometimes. Ok and when I see her in public places she be looking at me too so what do yall think do she like me or she still want her ex. O and she be writing on her myspace page she hurting and betrayal . So I think she kind of like me but she really in love with her ex what you think?
