Tad my XH was also always an "I'm right and everyone else is wrong" type of person. Over the years I became very much like him but I wasn't that type of person when I met him. We had an "us against the world" mentality and became VERY opinionated and critical/harsh of anyone who didn't agree with us and people said we could be very intimidating to be friends with.
I thought that was a great place to be because I had him in this very tiny, very "right" little world.
In retrospect it was isolating and sad. People now tell me that I am no longer that type of person, that I'm very tolerant of others, and much kinder and nicer. They tell me that this is probably "who I really am" now that I'm alone and finding my own personality.
You said you wonder if your wife will not ever admit wrongdoing because of this trait--and I say this exact thing all the time about my XH. Then I say to myself, would I really want to be with someone again who seems to bring out my intolerant and cynical side and who holds himself above everyone else to mask his own insecurities? And my answer is NO.
I'm happy about all your progress. Have a lovely weekend :-)
