DP went on an optional works 'do' yesterday with an overnight stay, apparently partners weren't invited.
He mentioned it a few months ago but nothing since, no date, no nothing. Rings me yesterday and tells me he's on his way and that he's staying overnight. I was gobsmacked, he hasn't said anything at all about this let alone staying overnight to me at all. I stayed calm and just said, I didn't know and he said, I told you ages ago, my reply was, yes but no dates about when or anything about staying over. He also let slip that someone's partner was going.
I'm not pissed about the event or stay, I'm pissed that he has had plenty of time to tell me and hasn't.
We don't live together just to clarify, am I overreacting?
