My way of dealing with unreasonable criticism came from my childhood, and it was primarily disbelieving the criticism, thumbing my nose mentally at the perpetrator, becoming either lazy/forgetful or flat out oppositional, and working to make myself happy regardless. I didn't see it at first. I just wondered why I was feeling like a teenager/dad relationship with my H. I knew it wasn't right. I knew he was certainly being outrageously unfair and I just didn't understand why. He's a smart guy and my partner for life, why is he acting like this? I could not figure it out. All my foibles were justifiable, explainable, not really all that bad, or not as bad as his obvious foibles, in my mind.
Don't have much to say about this except that I can completely relate this to my H. It's very unattractive in a 57yo man.
