I like this girl, but she is soooo confusing, what do you think?

i'm a 20 year old guy,There's this girl, i knew back in grammar school, but didnt actually know her, jus knew who she was, hadnt seen her in a long time. i saw her at the gym bout a month ago and we started talkin. for the next 3 days, she constantly IMed me, left me facebok comments, said she wanted to hang out, and gave me her number witout me even asking for it. We hang out, i try to make a move on her and she backs off. So now everytime i try to talk to her she jus says she has to go right away or jus doesnt answer, so i apologized for makin her feel uncomfortable and she said its fine. SO i saw her at the gym a week ago for the first time since we hung out. As soon as she sees me she asks me to go on the treadmill with her, then asks me if i wanna workout abs and legs wit her, etc etc. And she was going wherever i was going at the gym. anddd even asked me to go to a %26amp; p with her loll. but ever since then she hasnt contacted me once. im jus confused cause she sendin mixed signals

wow that is a tough one ha. Well she obviously has something for you or she would jusy not talk to you altogether. Maybe she thought you only wanted to "hang out" so you could mess around with her. And after you tried to make a move she wanted to take a step back and let you know she wasn't for that... it could be alot of things. I am a girl and I agree that we are confusing.
