You tell him NO ONE introduces your SON to ANYONE unless you are BOTH comfortable with it.. which goes for you as well.
And you hang up.
Don't argue, you put the boundary and end the convo.
Unless you have some leverage he's just going to keep goading you with it though... He has no reason to introduce her... You can get your L to include a "no paramour order", but he can always disregard that and you would prove he had disregarded it...
It's a waste of time negotiating with him
YOu can't file a restraining order on OW I don't believe, but you can always TALK to your LAWYER about this... Your WH WILL obey the LAW... that's your strongest leverage right now.
