2nd time around part 2

[NotAgainPlease]

Hey wants to chit chat about nothing. He will initiate it. But as soon as I ask a question. Not a relationship question he won't answer.
Last was he grounded kids13 when they were with him. I've asked 2x what he told them I'd I'm supposed to keep it going.
H had called when he did it to tell me but I wasn't clear what all it in tailed.
Drives me nuts. I know I was to stop when he initiates the meaningless chit chat. It's soo hard for me...
