Did anyone see the recent AITA on Reddit about this?
Basically, the bride and groom weren't inviting plus ones unless they both knew the person, liked the person, and would hang out with them after the wedding. Even if the couple was married. Bride's cousin sent back an RSVP that he wasn't going to attend because his fiancée wasn't invited. Bride talked to him about it said, "You can be apart for a couple hours?" Cousin said, "I can't believe you're asking me to celebrate your journey and love story when you won't recognize mine." He said he could be apart from fiancée, but he didn't want to be. Bride said, "Our wedding our rules." He said, "I realize that. That's why I'm not attending." Bride was upset that he wasn't going to follow her rules and attend. She clearly didn't think that someone would opt not to attend over her rules. She seemed to think her cousin was being unreasonable.
I did not see that one, but I have seen similar scenarios on AITA. Like I didn't invite the boyfriend/partner/spouse/child of someone and now that person won't come either. In my mind, that what happens. It doesn't necessarily mean you were wrong for your decision. A line has to be drawn somewhere. And some people would rather hang out with their spouse than go to your wedding alone. I have social anxiety. Unless this is a close group of friends, I am not interesting in going alone.
This happened before we were married but had been dating for several years. My husband was invited to his cousin's wedding. He asked if I wanted to go. I told him that since I wasn't on the invitation that I wasn't invited. He says well then that would be no fun. So he just RSVP'd no. He wasn't particularly close to that branch of the family. It wasn't a vengeful no. It's a "I have limited time and money. I would rather spend it with my partner than by myself at your wedding" no.
