I agree. I never invited anyone from my workplace to my wedding (30-ish years ago.) They were workmates, not friends or family, and there were about 25 of them, so I would have had to have invited all 25. (And if what the OP is on about is to be believed, all their partners too!) 😬
If I had invited just a few (or even half) and left the others out, the ones left out would have all been offended, so it was easier to not invite anyone from work. It was a small-ish wedding anyway, with just 32 guests, so my work colleagues weren't really too bothered about not being invited.
I did have an old schoolmate write a pretty shirty letter to me though about how she was devastated to have not been invited to my wedding. She was gutted that she 'had to find out about it from someone else.' 😖
The local newspaper used to have a feature where most couples who had got married in the town were printed in the newspaper. The photographer and the couples allowed it of course... And someone who knew this old schoolmate saw it, and told her 'guess what, ZOV has got married!'
I didn't write back to her. I hadn't seen her for about 3 or 4 years, and she had had 2 engagement parties some 4-7 years earlier, (YES 2! 2 years apart,) and her 21st birthday party, and I hadn't been invited to any of them. Indeed, we weren't even close friends ... Ever. We were just made to sit together at the same desk in primary school, as all the children had to sit in alphabetical order, and we were next to one another alphabetically. This is when we were 9-10. We hardly had anything to do with each other in senior school as we were in different classes.
But she was SO upset that I hadn't invited her to my wedding! 😬
