just wanted to say i agree with Alexzel completely and throwing in my 2 canadian cents (now worth ~ 1.1us cents :P)
The cliche: "When you love someone, set them free. when they come back, ....then it was meant to be"..... When you are willing to set someone Free... (even thought it hurts) then that is love. I am not saying you should give-up on the girl. What I am trying to say is, express your feelings. Do whatever you can to win her. In the end, let her decide. When she chooses the other, then, set her free. Whatever, the decission she will make, accept that. Whatever, which will make her happy
On second thoughts, Alexzel said it so much better....
