My WW is notorious to do the "let's meet up" and be all sweet, because she wants something. But the minute she asks or gets what she wants, she is right back to acting like a nut. So when you meet with her today and she gets down to the nuts and bolts of things, just say "let me think about it" and do NOT answer right away, even if you know the answer, just stick to the "let me think about it" response.
