okay here's my advice. She's out of your league. she knows it, you know she knows you know it. But forget about that. Just talk to her as if she wasn't . think about it, you're better off acting normal as if she wasn't all that. then she'll really notice you. If i were you, I would call her up, tell her how you were havin a bad day to start with and try to get a second chance with her. But don't make it so date-ish. Make it seem like you're old buddies again, and then make your move. Ig she was excited to see you its because she liked who you were before she left, not how you're acting now.
and seriosuly, two big things, don't make a big deal out of the modeling thing, she knows she's the shit and hot as hell, pass it off as thats cool but not why i'm here with you. and secondly, don't drill on the past. you see past she see's her old nerdy self, she wants to forget all that and enjoy her new life
