Which of these two girls should I choose? Please help me, ladies?

Take chances, makes mistake, get messy...lol I think you should ask her. I would like to bravo you for being brave and asking. If she says no go to the bonfire. I admire your persistent about your ex-best friend. If you do see her, talk to her, but if it seems like she doesn't really want to talk than don't push. You can tell if she does short answers and such. Anyway good luck
