OK, I 1/4-way believe you, but STOP TALKING TO HIM. These phone calls are getting you nowhere.

"I talked to him last this pm. I do find myself repeating myself again and again"

SO STOP TALKING TO HIM...

"He hasnt' called again so that's good."

If he calls again, guess what, you STILL don't have to talk to him.

"STBX, if you are confused, I'm sure the mediator can send you notes on our meeting. I'll see you at our next appointment."

Good idea to call your accountant :-)

Best,
Oldtimer
