Well, the fact that I didn't spin out of control after this conversation is either a sign that I'm detaching or that I'm getting tired of his chit... same thing? LOL
I can understand worrying that the diagnosis will define D rather than D being D and this being just a part of her... but I think he's more skeptical about any diagnosis actually being any help to us with her behavior or finding the right way to properly educate/challenge her. He's SUPER anti-therapy... yet he sees a therapist.
It's just another reason why he's not up for going to marriage counseling. "what are they going to do for us?"
He sees almost everything at adversarial odds. I am in favor of finding out what is going on with D - all of it. He is in favor of not spending money. He hates psychologists, I think they are useful but there are a lot of bad apples.
