Does gemini like me or playing me?

i was good friends with this gemini, then one night she really started to innocently let her guard down, it was nice and then "something" kinda happened between us (mutually), afterwards she acted really close to me, then a few days later she said i had motives (wasn't true) and for me to fck off. and wouldn't talk to me again, finally a month later we are back to being friends, she doesn't want to talk about that night and she is acting like she def. doesn't like me for more than a friend (flirting in front of me, acting mean sometimes, etc.) but is still acting nice as a friend--it's crazy. yet i can't help but think she has some interest (body language when were together, etc)..she also told me at one point she is emotionaly challenged..i really like her (for more than a friend) and want to keep her in my life. does she like me or not, should i just leave it completey alone and remain friends or try to chase her down-lol. btw, i'm an aries
