That really, really depends on the girl. There is no way of knowing, no magic answer to what a girl wants. I think in general girls want someone who makes them feel good about themselves, so compliments go a long way. But you never know, beyond that, what a girl wants until it turns out to be YOU.
it kind of depends on who your looking at! a girl looks for someone who would care for her, love her, and understand her! if she likes you then she sees who she wants, a girl decides for herself if she likes you, or if she's interested, just think about how she reacts around you and you will find out your self!
