So wifey and I are going abroad to see one of our favourite bands this weekend. We actually had tickets to see them last year but ended up being on our babies due date so we couldn't go so thought this would be a nice way to bring it all full circle. Anyways - since we have had legit zero days just us together since July last year we decided to make a weekend of it and take advantage and do two nights as her mother will mind the baby for us. I had envisaged taking her to a nice restaurant and seeing some sights and mayne take in a show on the first night, then the concert and drinks the second etc. Her cousin (who I have met twice in 14 years... wedding included) lives in the same city so my wife asked her if she had any recommendations for somewhere nice to eat. I'm not sure how (or why) but the cousin decided to book a table for us and her husband for dinner on the first night. They don't even know where in the city we are staying so likely travel involved but anyway. Now look they are nice people - but I wanted a chance to reconnect with my wife, relax and have a fun weekend so when she told me 'the plan' I suggested she go back to them and say look, sorry but we already had plans etc. But she thinks that makes us the assh*le and won't do it. She asked if it was really that bad? To which I said look I'm not going to apologise for wanting to spend time with her, and not her family the one opportunity we've had to do so since 2024. I told her how rude and presumptuous it was of ger cousin to make plans for us all, that we have never hung out with them before and there is a significant age/interest gap between us, and that I wasn't going. The net result is that now instead of being a few days away from what should have been a great weekend away we aren't speaking to eachother because she's too polite to cancel. So - AITA ? EDIT - Just to add here my wife doesn't want to go to dinner with them either. We planned the weekend together.
