Not sure why you’re bothering with her.

Quote
For example, I am driving, and she asks me to take a turn, and it turns out it's incorrect, so I tell her that was the wrong turn. She goes ballistic and accuses me of calling her a liar, "You know you are being extremely disrespectful." She regularly threatens me that she will note down whenever "I make her mad" and then revisit it later, which will undoubtedly lead to divorce. She still refuses to see a different IC.

You know, there’s millions of incredible women out there who can say “I was wrong” rather than gaslighting and emotionally abusing their husband.

You seem to reiterate with pride how you force yourself to ignore her behaviour.

You might think that’s attractive, but to her, it’s not. It just makes her despise you more.

If she says “I will note it down if you make me mad”, perhaps you could suggest that will help her when she finally decides to talk about her anger issues with a therapist rather than blaming you.

Or perhaps respond with “That will mean we have log of all the times you gave me incorrect driving directions but you were unable to admit your mistake.”

There’s a very fine line between an unaffected, calm man - and being a doormat.
