At your age, most girls end up changing boyfriends like they change shoes. Just wait it out. You said that you were really good friends before all of this started. Believe me, that's a terrific sign. Eventually they all come back around to their 'friends' because they realize that those same qualities that made you a great friend will make you a great boyfriend. Sounds like she's got something there for you but you'll just have to bide your time. Yeah, I know - that sucks but look at it this way. While you wait, you can date with reckless abandon. Just try to stay in the periphery, be nice and willing to listen when she comes back around (and she will). Good luck. Enjoy your birthday!
