Just some context! In my city, there's a tradition of throwing wedding socials to raise money for the bride and groom. It's basically a large fundraising party where everyone gets together and buys drink/raffle tickets to support wedding costs.

I'm getting married in 6 months to an amazing man -- we've been together for almost 3 years now. We're all a part of the same friend group, we all knew each other through school growing up, and I also knew my ex-boyfriend (of 6 years) from that friend group. It's been a few years (I dated my fiance shortly after we broke up), but I know he's not over me; I'll get texts still whenever he's out drinking, and he's expressed that it's hard for him to see me moving on with my fiance even years later. It's caused a few rifts in our friend group and at times I've even asked my friends to not include him because of his behaviour.

It's a really tight knit group, so obviously everyone (except my ex) is in the wedding party. This basically includes all of the friends that we both grew up with, and definitely all of his friends. My ex hasn't been doing well lately, and everyone's been saying he's going through a rough time. I wanted to have my social on St. Patrick's Day, but everything was booked up, so I had it two weeks before which HAPPENED to be on my ex's birthday. My ex was invited (everyone in the friend group was), showed up, and seemed to enjoy himself.

The other day, one of my bridesmaids said they felt bad that he had to choose between going to my wedding social or essentially doing nothing for his birthday, since all of his friends had to be at my social and wouldn't have been able to do anything with him. Honestly, that didn't even cross my mind. Like, I think it's been way too long for him to still be hung up on me, and while I could have had the social another day, it's my wedding and it's not like I need to cater to his feelings just because he can't move on. Apparently he had a really hard time at my social, but I wasn't really checking in on him so I don't know for sure what that was about.

AITA?
