I know it seems that she is the only one for you right now. But chances are you WILL find someone else in the future. I felt the same way about a boy when I was in high school. Now, I am married to a wonderful man and I couldn't imagine him not being in my life. I seldom think of that other guy. In fact, I don't even know where he is right now.

That being said, right now, it hurts. I think right now, the harder you persue her, the further she will run. If it is meant to be, she will come back. You're a great guy, if she can't appreciate that, you need to find someone who will.

Try to keep yourself busy tomorrow.
