Hi man; That story seems a little familiar to me...
Here is the story: (long story made short)
SO I met this girl and started playing with her , I got her fun , got a lot of IOI but couldn't close, I went out like 3 more times and just couldn't close, later on I found out he was dating this other guy (like 2 months before) She finished being his GF, but She called me, she told me she don't care about this guy , etc..., so I started feeling things for her (A lilttle bit of One-itis) so I started like loosing her up, so I tried to play hard to get (Yeah I know, is fucking hard, but you have to do it , I think you are in this situation) , but I couldn't the girl was 24/7 in my head, I met her in a Party and she was nice at the beginning but then she started talking to 20 other guys just to make me jealous(actually she did pretty well , I was fucked up that night, but didn't showed interest on her, either, all through I was burning in the inside. I guess that was an important thing.) Finally I could and I Avoided talking with her for a few days and she start playing nice with me , she told me she dumped his bf, and she wanted to meet again.

She Told me she was going to call to night, lets see what happen.
Okay anyway , I think you are kind in the same situation . (I don't think your going to the LJBF) But I think that because you like the girl the best thing you can do, Is play hard to get, until you see she is giving you nice IOI (Don't be a jerk , just don't call her and you will see she will send you a message at least.) Yeah It will be hard but Is the only way to win her back , think like this:
If she want me she will contact me , if she doesn't , she lost her chance.
I hope this helps you. IF you have any question just send me a PM.
Sorry for my english
