Sadly, that's not uncommon. I've heard it so much from so many people. Often phrased as "the only thing I did wrong is marrying you to begin with." I think a lot of it is defensiveness and justification, but those mechanisms only work so long because they're thinking errors.
I am even more saddened by the fact that I accepted that line of thinking for so long. I accepted that I had problems and was not good enough...
