It's hard because if she isn't interested already then it probably won't work out anyway. I've been there and it hurts like hell because you just want to be that guy for her. You'd think there's just no one like her. As of now it would seem that way but things just change in surprising ways. If you really aren't the one for her, you'd find someone much better for you and it would be so easy being with that person and she'd wanna be with you as much as you'd want to be with her which is awesome. Anyway, hang in there buddy.
