BIL came over for Christmas dinner, which DH (a chef) had spent literal weeks prepping when not at work. I made conversation with BIL while DH cooked. BIL complained about the food and told DH he'd have been happy with frozen pizza. Following the inevitable fall-out between DH and BIL (I took DD- then 6mo- to the bedroom so I wasn't stressed and she wasn't listening to it), we all went for a meal a month or so later- BIL's suggestion- I thought as a making-up/apology thing.
Yesterday, BIL told DH that he was still angry re Christmas and that it was really awkward having to talk to me while I was breastfeeding. I'd put Christmas far behind me/almost forgotten at this point.
AIBU to feel like BIL is just seeking an argument over nothing? Any idea why he'd say all this now?
