Simply tell her you don't think it's appropriate to be having that kind of conversation given where the two of you are at. And if she pushes it, tell her you're not GOING to have that kind of conversation given where the two of you are at. Believe me, I know where you're coming from. I have to watch my wife walk out the door for work every day, and she is a fine-looking woman indeed. I don't need that kind of hassle. Fortunately I think she's sensitive enough not to ask, because she always did when we were "married."
