@Starsky309: I do appreciate the advice. And I really am trying to follow it. Part of the problem is that I haven't even had a chance to read the books yet, so I feel like I'm flying blind here. I'm a pretty conciliatory guy by nature, so a lot of this stuff feels very counter-intuitive.
I hear what you say about me giving her the idea she can still have her cake and eat it too. I will be toning down the pleasantries and upping the unavailability.
