Im 20 year old guy and i have feelings for this girl, but i just cant tell if she feels the same towards me?

met this girl at the gym bout 2 months ago, for the next 3 days, she IMs me, leaves me facebook comments, says she wants to hang out MULTIPLE TIMES, sends me her number without me even asking for it. We hang out, i try to make a move, after i kissed her once, she turned her head. I apologized 2 weeks later and she said its fine. She hadnt contacted me at all in the next few weeks(while i had been tryin to), only time was when she saw me at church on easter sunday, and as soon as m was over she texted me saying I JUS SAW U, HAPPY EASTER. so i saw her at the gym lasweek and she kept following me around kinda (not in a bad way) and wanted me to go to grocery store with her? anyway, she asked me get coffe last weekend, so we went and it was good. STILL, she never contacts me first like she used to BEFORE we hung out?Las week i see her at the gym again, AS SOOON as she sees me she goes I BEEN TRYIN GET UR ATTENTIONN BUT U DIDNT HEAR ME, IF U DIDNT DO ABS YET, U WANA COME DO THEM WITH Me
