The question is "Why did you just leave me there....not address things before?"
Surfer,
I think that statement is typical of a WW. It may be true, you may not have addressed things before, but now she's using that as yet another reason to paint you as the bad guy. It's like Sandi has said before, she (Sandi) doesn't know of any woman who's ever divorced her husband because he didn't clean the house (paraphrased).
