Currently, I’m polite to friendly with all of them. No outstanding conflicts. It’s sometimes literal kitchen table poly with one, and the others I only see at like parties and such.
Some years ago I had two partners that absolutely did not get along with each other, and that was rough. Recently I was able to do a dinner with 3 partners and everyone had a good time.
I try not to make a big deal about folks meeting. I try to model after meeting your friend’s friends.
I think I’m somewhat in the same boat. I’ve got one metamor that I talk to and is even in my Pathfinder game with my partners and seems to have taken an interest in me.
The others I get along with, but we don’t talk too often.
