If your partner’s mom starts talking trash about their ex, do not take the bait and join in. If you stay with this person for a while, you will likely have all the time in the world to learn how to gossip with them and get the dirt on Crazy Aunt Linda, but the first time you meet them is not the time. If gossip is their thing, bring up some celeb everyone can dish on or something else impersonal to bring you closer together. But when it comes to this new family, stay super neutral and don’t take the bait. You want this first meeting with the parents to lead to another time, right? Keep it classy.
