As above really. Dh mentioned months ago we'd been invited to the evening do for one of his colleagues 'in July', and he wanted to check I wasn't working. I checked my rota and I wasn't, so agreed, potentially (I've had health issues so was no way able to guarantee attendance) to go. I instantly forgot the date and he didn't write it on our wall planner, but it was in his diary. He would be the only person I know there, I've never met the bride or groom.
Anyway, last week I had some really good news re my health (have been poorly since January but hugely improved in last few weeks). I shared this with my friends who have been uber supportive of me during this time and one suggested a night out (just dinner, I'm too old for clubbing and not well enough for alcohol). Friend suggested 3 possible dates this week, out of the 3 I knew i could do 2, but checked with dh there was nothing I'd forgotten (memory issues have been a thing) and he said no, and that he was pleased I was going out. We picked this Saturday, there are around 6 of us going.
Tonight dh has said he's looking forward to going to the evening do with me. On Saturday.
He remembers our conversation re checking dates, and that he said we had nothing on, but is upset that I'm not willing to cancel from a dinner which has basically been arranged for me.
AIBU to send him on his own to the evening do?
