Basically I rekon if she's not interested in you she's not worth puttin in the effort. Cause when you put in loads of effort you start "acting" and you're not really yourself.
She's gotta like you for you.
But if she shows interest, then keep it moving y'know. Don't just leave it at that "friend" stage. Otherwise you become "friends" and that's where you'll stay.
So from the start, if she seems interested, keep the momentum up, give her compliments, meet her on a social level and perhaps meet up with her without the
other people, that are always there!!!!
Then invite her to take it to the next level Y'know. If she likes who she's with, then she will.
My Motto, "
Make 'em laugh, make 'em c*m, and they'll be yours forever... "
