We recently went on holiday to a place where I have a bunch of family. My husband agreed we could go and we would see them as we wanted on and ad hoc basis.
Last year we went to a place where he knows a lot of people and saw a bunch of his family for some dinners etc.
Both times we stayed separate and didn't over plan anything with family and just arranged things for the days we both wanted to. Last year there was no issue.
This year however it was very different.
We made plans ( usually the day before or day of ) to go for dinner or lunch. I would talk to my husband in detail to make sure he was happy to do it. Then whenever it came to getting ready he would start getting stroppy and saying he couldn't be bothered and didn't want to go after all.
He did this every time we had both mutually agreed on plans. I even cancelled a couple of times because of it.
I understand that things change, but he did it every single time. After he had agreed. I think it was really harsh. I see his family all the time and live away from my own family and I don't complain about it. He couldn't even be bothered to stick to plans when he'd also agreed them and just made me feel bad the entire holiday with his grumpy face and attitude.
