Help me out!

I like a girl down the street but she has a boyfriend (she says that it sucks that every time i come back that she has a boyfriend) should i just leaveit alone or go for her

As long as she's in a relationship, leave it alone.

Seriously...move on or wait. She's in a relationship and if I were you, I wouldn't want someone who doesn't have the courtesy to break up with someone before they say crap like that to a different partner.

Are you kidding, Brian? That seems like an awfully childish thing to do, and your profile says you're 18.

You can wait for her if you really like her that much. or you can move and maybe find someone who is better.

and brian thats a no no.
