I think this tells you that, for good or bad, she cannot, as hurtful as they are, ignore them completely. She knows how you feel, so doesn't want to discuss it with you further. Please don't push, because then she will feel even more in the middle. Some things just can't be resolved so easily.
Hi Quandry
You may not have noticed, but the thread in question is almost two years old. :)
My wife did read the book, "Toxic Parents" and it was a major eye opener for her as she was able to read exactly what she had been feeling and got the perspective from why her parents act that way. I'm proud to say that she has largely addressed this issue and now keeps up with friendly family news, but doesn't go out of her way to seek approval from her parents, she now knows it will never come and is fine with that.
