One other thought is the % of the behavior in question? Not every squeeze, hug, or flirt has to end up 'baby making'.

Maybe you could join with behavior in kind? That doesn't necessarily mean trying the same with her, men are wired differently. Without going into the details, keep her off guard verbally.

Good luck.
