I think you've probably seen too many romantic movies. Nicholas Sparks perhaps? :) Bring on the world and I'll wait forever and it will end up all right? It doesn't actually work that way and you'll hurt yourself in the end.
I already talked about the giving up bit, and it being different than letting someone go, but obviously that didn't sink in.
In any case I do hope it works out for you, but that if she doesn't come around, I hope you eventually realize what everyone has said.
