So we are only allowing guests to bring plus ones if they are in relationships, since our venue is small and budget is tight. We have had an unusually high acceptance rate, so we are already at the max of what we can accomodate in terms of guest size. Well I noticed that one of FI's relatives listed herself as single this weekend on Facebook. She had RSVPed that she was bringing her boyfriend at the time, and we specifically only put his name on the invitation, not "and guest". And when she originally asked if she could bring her boyfriend a while back before we mailed out the invitations, she mentioned that she would really hate it if she "had to go to another wedding alone". We clarified for her then that we were only allowing guests to bring their significant others if they had one.
My numbers are due to the caterer this weekend. My question is, if she doesn't reach out to us by then, is it okay for us to reach out to her and let her know that we see she is no longer in a relationship? Since our RSVP date just passed, I'm thinking she may not know that we haven't already sent in all of our numbers to the caterer. And considering that she made a comment that she didn't want to go another wedding dateless, I could possibly see her trying to fill in with someone else. And we've already said no to so many other plus one requests from our other guests, that I think it would be unfair to them if she got to bring one given the situation. I would be happy to let it slide if she wouldn't know many people there, but she'll know all of FI's family, which is quite large.
