Should i stay with this girl, who is giving me mix signals?

So i am like in love with this girl…But i don’t think she still love me.. or maybe i am wrong. we went out for almost for a year and i broke up with her… lets just say i was stupid, i left her for someone else. After a few months i started to talk to her again and finally broke off my gf. Thats when i realize that i still love my first girlfriend. She was my first love and i don’t think i can leave her. So when istarted talking to her again and i told her that i still love her and she told me that she moved on, but i know that wasn’t true. So one night we talked for so long on the phone and finally she broke down and told me that she still loved me and still want me back. she told me that will break off her current bf slowly and come back to me. So after a few days later i did something stupid, i was being too pushy?? so i pushed her too much on getting back with me…. so we had several arguments and later she told me she didnt’ want be friends anymore… so i did as she told… so we stop talking for two months and after that two months i started to talk to her again… and she was cold to me first but later she got a little nicer…. i also found out that she broke up with her bf… So know we are talking and joking as usually like when we are together… but i know some difference in her… she never start a conversation or call me. i have to make the move to talk to her, when we talk we talk for hours like 5. But sometimes i get this feeling like she lost interestes in me and doesn’t want me anymore. like whenever i want to hang out with her she would say no.. but we aim alot..

So the deal is… when her mentor told her to draw someone sculpture your life, she draw a picture of me and her when we first met…... does that mean she still love me??

when we talk on phone, she and i would have a nice conversation and we wouldn’t stop… but as soon as she goes on aim, she becomes something else? or may i am just reading it the wrong way…
is she wrapping in her cocoon so that no one can hurt her again? or she is totally over me and want to have nothing to do with me?
i really really love her,,,, should i move on?? or keep on waiting… i have been waiting for her for 5 months already…
