Not so much an AIBU, more of a WWYD but posting here for traffic. DH and I have been together for over 35 years. We see this particular friend once or twice a year (she lives in a different country, I’ve known her from school age). Every single time we see her, she brings up a huge, public stupid drunken argument DH and I had 30 years ago in a pub on NYE where I was in the wrong and made a fool of myself (I’d assumed he was having an affair - he wasn’t, he was actually planning a really fun ‘experience’ type gift for me which involved lots of clandestine phone calls!). I apologised and we agreed to draw a line under it. I cringe every time she mentions it. I’ve tried everything I can think of…laughing along with her, breezily brushing it off, redirecting the conversation, telling her it makes me feel uncomfortable, asking her to stop talking about it. DH has also asked her to let it go but she still mentions it every time and we are walking on eggshells as we both know she’s going to drag it up again! What would you do? Any ideas welcome. We text and call regularly and it’s never mentioned - only ever face to face.
