Wat is this girls deal? does she like me please help?

we've known each other since we were both in the 3rd grade. now we're both juniors and in that length of time i've notice some things that i can't figure out. like back in the 3rd grade i remember her askin if a gf or something and when i told her no she said to talk her. than in the 6th grade we were at a dance and she came over to talk to me after seeing that i was alone. before i left the dance i gave her the flower that was meant for my date who nevered showed. later i learned that she has it hangin up on her bedroom wall. now that were both juniors i would notice how everyday she would walk past me sometimes glancin at me out the corner of her eye. finally i decided to ask a few of her friends wat her deal was. when she found out that i was askin about her she got her friend to get my number. then i started to get txts tellin me that she did not like me and that she was only walkin past me to go get some water. afterwards she kept on walkin past me every day. please help wats her deal
