@Joconor,
Normally I don't respond seriously to repeat posts cause it makes me think the poster is stupid for thinking we are stupid and won't notice he is asking the same thing and hoping to get the advice he wants to get as opposed to honest advice. That said, I will reply to this post since it appears you had no responses to the post from yesterday, although honestly you should have given it a few more days or posted again under the other post to bring it to the top. Whatever.
As for your problem, I would suggest you get over this girl quickly and find someone else. She is either playing with you or simply being a good friend and you are reading more into it than you should.
