It wasn't me that you had the convo with, but I remember that one. Actually, it's not as complex as you're making it out:
W: I just feel like our whole marriage is crap. I don't think I ever loved you Muddle and we got married for all the wrong reasons. M: Ok, I guess I can see how YOU would feel that way. W: Oh, how "I" feel, so I'm wrong then. You're so condescending.
Pretty much covers it.
I have tried to look at things in different ways - even to the point of agreeing that "it certainly feels that way" but generally I validate by saying that I understand how she could, or that she does feel a certain way. I feel cornered all the time, and I think this may be an area where I need to do a 180 - she starts conflict and I try to pacify
