I will admit it was a very interesting discussion! I was amazed at how misinformed he was/is. If nothing else, at least he now knows why I don't get involved with him and family issues any more.
I used to have a horrible temper. He's not worth it. This trip is about my mom...not him, not me and not his wife...most assuredly. And it certainly isn't anymore. That was crystal clear when he left today!
