I really like this girl in my class, and I have the confidence to talk to her and I am pretty sure she likes me at least a little bit. But I know she has a 22 year old boyfriend (she is 16). So is it OK to flirt with her? And is there a way to get her to like me more than her current boyfriend?
Its never too late for anything. Any girl can be totally swept off her feet. If she finds it in you and you instill the same confidence in her as her boy friend then it really doesn't matter too much.
As in to make her to like you, the balls totally in your court, I can't comment standing on a blind corner. But just remember if you do go for that, don't do antics that makes her remember the current dude; start being more closer "friends" if you can. ;-)
