Sorry if this sounds petty. My son was at a neighbors house today at a birthday party. We are all good friends, parents and kids etc. I called round for tea/ glass of wine towards end of kids party. Neighbors said there was a tonne of food prepared and did we want to stay to dinner? OH usually cooks Saturday, so I called him, checked had he started dinner. He hadn’t so I asked if it was ok that we stayed? He was invited too but said no, he’d stay home but we should go ahead. However when we got home he was in a huge sulk... said he’d been left having dinner alone and that I’d been unreasonable phoning him and ‘putting him on the spot’. Kids now upset as we are fighting... I’m upset as I feel I should have the freedom to choose my own dinner occasionally. But he says I’m selfish. AIBU or more to the point IHBU?
