I’m annoyed I’m feeling I’ve done something wrong when I all I wanted was him to have a nice bloody day!
Had you both discussed what he wanted for his birthday?
I can't speak for him but I will tell you what birthdays are like for me in case it's relevant and gives some insight.
I don't celebrate my birthday. I'm 51 now and I haven't celebrated it for 33 years. There are many reasons for this, which aren't relevant here.
That doesn't mean other people haven't tried at various points. And I always went along with it because they were only trying to do something nice for me and i didn't want to disappoint them or appear ungrateful (and sometimes they just didnt listen and went ahead anyway). It also sounded nice weeks in advance and i often liked the idea of it and thought id probably enjoy it when it happened. I was probably quite enthusiastic at points. But, in reality, I found it very overwhelming and struggled hugely. I felt overwhelmed, stressed, pressurised, guilty, ungrateful. Horrible. Even when surrounded by friends and family.
I know that other people only have good intentions and want me to feel loved and to have a nice time but my experience of it is very different to that.
I'd have a proper conversation about it.
I know some people love to have a fuss made of them and other people love to make a fuss of others. And others don't. And it's a real never the twain shall meet situation.
Oh and I would also ignore 'hope you had a lovely day' messages from someone I felt I'd let down. It just be so overwhelmed I wouldn't be able to process it properly. I'd be aware they'd tried to make it nice and I'd feel I'd ruined it but none of it would have been a choice. And I'd need time to regulate my feelings on it.
I also find other people's birthdays very difficult to navigate too because I'm not sure what I'm expected to do for them because it feels like an alien experience that others seem to love but triggers a fight or flight response in me.
So, I'd also say that I'd celebrating your own birthday is important to you, he just might not be the right person for you.
