I had a very similiar relationship with a girl. I was very good friends with her but she didn't want to date because college is right around the corner. So basically one night I just told her I wasn't going to talk to her anymore because it sucked so bad knowing that we could have something and us just letting it slip by. Sure enough a little over a week later I get a call from her... and now things are great kinda. We hang out almost every night.

BTW- She's the girl in the member's pics threads.

My advice is to let her know how you feel and if she feels differently just say that you don't want to be friends and that won't work because it'll be a constant reminder of how you could have something great. I had to ignore some pretty tough text messages and stuff, but it worked out for me. The way I looked at it; you'll either get the girl, or get over the girl. It's the ballsy thing to do.
