I can't stress this enough...
You're right...Treat her like every other dick tease you've ever met...Or at least how I treat them. Pretty much just ignore the bitch.
Well, don't completely ignore her or it'll ruin your game because she'll know that this bothers you. Just pretend that she's an old lady with a goatee and big black mole on her cheek, be really nice and polite while doing so (so she doesn't know what you're up to) and two things will happen...
1. She'll get put back in her place and start to have doubts that she's God's gift to men.
2. 90% chance you'll end up fucking her if you ride this out a couple months...EVEN IF SHE STARTS FLIRTING WITH YOU BIG TIME, RIDE IT OUT FOR AT LEAST ANOTHER FEW WEEKS.
