BF of 2+ years helping me out today with taking some stuff to the local tip. BF’s ex-FIL works there, BF usually chats if he sees him, but uncomfortable for me but basically okay. Today as we were queuing, I had to stop and wait on a hill, and accidentally stalled the car as I got anxious and a bit flustered when I went to move off. The FIL was nearby and made a ‘clever’ comment about my driving which BF responded to with, “I’m saying nothing!” and they laughed. It sounds silly, but I felt quite upset, as it felt like they were laughing at me, together. I felt humiliated. BF insists he wasn’t in the wrong because he ‘didn’t make a comment’ - but in fact, by saying what he said and then laughing, he actually did, IYSWIM. Overthinking alert??
