From the sound of things, you got the game all fucked up. You can still talk to her, but you should be going out and and exploring other options, if nothing else to increase your social value and to let her know/see you have other options!
If you swoon over her she knows your not a challange and you haven't changed abit since the first go round (I.E. she will be bored soon and you will be back to square 1) It's called cat-string theory (cat gets bored when it finally catches string). Now if you build attraction in this girl, but she knows (hint, don't blatently tell her)you have other options and you don't want to be in a relationship right now, It will drive her crazy knowing your not hers. Don't and the relationships in her hands...good luck!
p.s.
Blaming women for for something, is like blaming fish for not biting..... It's not their fault!
I hope I don't come across like ass, but it will hurt more when she smashes your heart!
