OK, Jase, how's she fucking with your heart? Details please.
If she's a tease then that's one game plan.
If she's got other guy's after her and she's trying to get you to play "Let's you and him fight over me..." then she's a cunth and that entails an entirely different gameplan altogether.
What is your objective? Have you boffed he yet? Do you love the girl or do you just want to bang her? Does she have a sister?
