@gilly04,
There's a girl code? Sheesh.
Go after whoever you want to. It will work out, or not. Don't be beholden to some nonsense 'code'.
This is not insensitivity toward the other person (and I don't advocate insensitivity; please don't misunderstand me). But don't be hanging your behavior on junk that
Cosmo magazine and the like made up, to make women even more insecure.
