I actually think that with this girl you have a chance if you wanted.
Didn't you want to go paint-balling ?Movie is boring,man.
Like I said :
1)Don't mention the "guilty" stuff she was talking about.
2)Make her realize that you're just having fun and not chasing her.
3)If she mentions it,tell her :"I get it,I'm not your boyfriend,doesn't mean we can't have fun,I promise not to do anything you wouldn't agree on".
