You've tried patterns, eliciting values, being friendly-touchy-kino, maybe some GM,
Smooth, even being a bad-boy hasn't worked. Then just start ignoring her, be rude, if she
asks "why?", say because you just want to, you'll just do what you want. She
just might start making passes on you and if you keep on just ignoring her and pushing her
away, it'll make her crazy and eventually you can do whatever you want with her. But don't
use it unless really nothing else has worked so far. Remember, she hasn't responded to you
favourably, so she's on her way out anyway. But if it now turns out that she is the kind
that likes a little kick in the buttocks every once in a while, well good for you:)
