So we just found out that one of the married couples we were inviting to our wedding are getting divorced. We had already told both of them that they were invited, and we're friends with both so we would like for them to come. It's a pretty calm separation and they claim it won't be awkward if they're both there.
However, one of them implied that she would like to bring a plus one to the wedding (since obviously she and her husband won't be going together anymore). But our guest list is already longer than expected, and we didn't budget for any extra people. And if we gave her a plus one, we'd have to give him one as well.
Am I wrong for wanting to tell her that she can't have a plus one? Is there a way to tell her nicely that she can't have one?
