Ask if she wants a relationship (which I doubt because she's toying with you) and when she says "no" tell her to screw off then. When she gets all offended tell her she's not being very sensitive of your emotions so why should you be of her's?
Although telling her to quit it the ignoring her if she doesn't from then on would probably do the trick alone.
