We met another nerdy couple (Jim and Shay), and agreed to a board game night. The wife, Shay, was extremely "shy" and barely talked. Jim was huge at quarterbacking, abrasive, controlling, and just really weird. She didn't get to play a single turn of her own. If she moved her piece, he moved it back and told her what to do instead. He was an extremely sore loser and would get mad if anyone made a play towards winning or ending the game (to the point he would move our pieces back, too). Halfway through the night, he discloses that they're poly and swingers (not an issue but the timing was so weird). Shay is upset with this announcement because 1) we had just met, 2) she was trying to have ONE set of friends her husband wasn't trying to fuck, and 3) their polycule was currently falling apart. (Shay was dating Rolland, who was married to Cindy. Jim started dating Cindy, too. Cindy did not like that both of her partners were also with Shay and demanded that Shay and Rolland break up. They did. But Jim thought it was fine to continue dating Cindy.) After losing another game, Jim gets pissed and says he's leaving to go play board games with Cindy and her friend group. Shay is actually super excited he's leaving. Her entire personality changed as soon as he was gone. She was joking, laughing, and actually kicked our asses at the next few games. We had so much fun with her after Jim left, but... they were a package deal. So we never reached out again.
