This may be me over thinking things but I’d welcome a second view.
My DP had a night out on Saturday and got home just after midnight. Yesterday, I saw one of our neighbours, a lady who lives across the street and she said hello and that my DP was a bit merry on Saturday and did he have a sore head the next day. I was in a rush and said he was a bit groggy.
When DP got home from work, I relayed her comments and he casually said ‘oh yeah, I bumped into her just as I was about to get a taxi so we shared one to split the cost and she invited me in for a night cap’.
AIBU to feel confused why he didn’t tell me about this himself? It’s not a neighbour we have socialised with before beyond pleasantries in the street!
