DH and I are quite friendly with someone I work with and her DH. We often do things socially with them. We had arranged a little while ago to go out for a meal with them next Saturday. She text me yesterday to check that we were still OK to go, I checked with DH , he said it was fine so I confirmed with her.
A few weeks ago, DH had told me that we had been invited to a gathering on Sunday evening with some people he knows through his hobby. I said that I would love to go and it would be nice to meet these people.
Anyway, today he went to do his hobby and came home and said he had got the day wrong. This gathering is on Saturday. I said that we would be unable to go as we already have plans. He said that he understands I'll feel awkward cancelling but that this it what we should do because we see this couple regularly and this gathering is a one off. I've asked why I should be put in a position of cancelling and feeling awkward because of his mistake. He announced that it doesn't matter because he's definitely going to the gathering. I contacted my friend and said that DH would no longer be coming but that if her and her DH were happy to go with just me, I would still love to go for a meal with them. They're fine with that. As far as I'm concerned that's an end to it. Next Saturday I'll do my thing and he can do his. He's gone ballistic though and says that I am selfish, childish and a people pleaser that puts everyone else before him. Am I being unreasonable?
