I'm glad to see that you didn't take the bait of getting into a heated discussion w/him. Sometimes we just have to put it out there in a very nice and civil manner to get the answers we need.

They do seem to want to drag you into a fight. Not sure why, but it is what it is. The sooner you stop allowing that, the sooner it stops. Just so you know
In my case, it hasn't yet. But it's close. She's instead getting her H to pick up the fight and her daughter. But that will die down as well - just a matter of time and me not responding. It's the same for you; stop responding and you starve that fire.
