Ladies how would you handle this? You’re with your husband of 4yrs at an event. He introduces you to an acquaintance however he says his ex wife’s

I would tease him about it the rest of the night. I would go up to friends and other people we both know, and say, "Hi! My new name is...__________" 🤣🤣🤣

He was probably with her the last time he saw this person. While I wouldn't be thrilled I wouldn't let it ruin my evening either.
