I think what J5 said is really important, you have to make a number close or e-mail, facebook even (but preferably number), because if you start turning up every weekend trying to get with her then like J5 said, you become an AFC and her income!!!
The only way you wouldnt become AFC if you kept turning up was if you were gaming a bunch of girls and playing them off one another.
When you turn up, just be casual. Say hi to a couple of the girls, when the girl you were gaming comes up, dont ask for the free dance straight away. Just stay cool, chat to her, have some fun.
Then eventually she will be wanting you to go back stage. Then you go for the number close after she does her thing!
Good luck with her.
