I call OW "That Arkansas Hillbilly". I doubt seriously my H ever calls her that, and I have never said that in front of him.
I am hesitant to call my H on rude behavior. I did the other day, and noticed it was something about food, and I realized he is a selfish pig!
We were making pizza, and like a child he decided to make a stuffed crust pizza, and he used half the cheese intended for 4 small pizzas on making one! It is like the reasoning switch is turned off with the empathy switch.
This goes with what Snodderly said about money, and not wanting to share.
Glad to hear your ex was polite!
