WTF cares? You're young, there's plenty of girls out there. Even if you two got together, we're not talking anything permanent here. Forget about her, and WHEN she becomes single again, ask her. Don't give me this "I'll always be wondering what if" BS. Oh and grow some balls now before you wake up in 10yrs and realize all the life you've missed out on.
"Oh Lord it's hard to be humble, when you're perfect in every way. I can't wait to look in the mirror, cause I get better loking each day. To know me is to love me, I must be a hell of a man. Oh Lord it's hard to be humble, but I'm doing the best that I can." Mac Davis
