Yeah, I'm sure that was a big part of it, but even two years into our marriage 19 years ago, there was never any "I'm Sorry" for anything AT ALL. Never an attempt to put us above HER, at least in the arena of putting closure on arguments or disagreements. You're definitley right however, that a lot of had to do with what I was or more impotantly WASN'T doing, but it was really like trying to play the game "Whack-a-mole" with her. I'd work on the last thing she bit&hed about, and then just as quickly she'd change direction, and uncover the next thing I was inadequate at. When we went to counseling in 2033, I listend intently, and tried my best to undo the injustices. She made not a single improvement of attempt. I KNOW I had stuff to fix, I admitted it, and went about it. She admitted nothing, and went about fixing.....you got it...nothing.
That being said, though, what you say is in all the literature I've read, and it does have a lot of truth to it.
