I'm sorry ahead of time because this is probably going to sound harsh...
But fuckin' UNFALL FOR HER dude. She doesn't want you. You could either get all emo about it and cry for weeks- which will do nothing for you- or you could just say fuck it, and move on and get on your game sooner than later.
Trust me man, I've been there and you can't just make someone want you the way you want them no matter how much you wish it were so. They either do or they don't. It totally sucks, but that's the way it is. I hope you don't think I'm just being a dick, but I have seriously been there many times and felt taht same hurt- and dwelled on it for a long time to no avail. The sooner you give up on the dried up well, the sooner you can strike oil somewhere else, nahmeen??
All you can really do as a man is take it in stride and move on. Don't hold on to any anger or hate, because it's not her fault she doesn't see you the same way. Just try to accept it, shrug it off and move on. Best of luck brothaman, shit sucks but it could be worse!
