I've alwasy been sketchy about chicks like this to be quite honest. If she has a boyfriend and is making out with another guy (you), what makes you think she won't do the same to you, if you guys do happen to get together? Once a hoe, always a hoe in my book.

Honestly, I wouldn't worry about that dude until you turn 18. Like Kaneda said, it's a pretty damn big offense if he does fight you. I'm 23, and I would never do something so damn stupid (Then again, I'm also not gonna be working at Taco Bell in 2 years either, but that's beside the point...).

Either way, fuck that dude, if you and this chick has mutual feelings, you should act on them.
