We invited FH's coworker and his long-term gf to our wedding but they apparently broke up so FH told his coworker that he could invite a different coworker. I got upset for a number of reasons that I won't get into, but he said the other coworker should've been invited because they got close after the invites went out (I wasn't gonna argue with him on that because he should be able to invite his friends to our wedding). So I told FH that his other coworker should get his own invite because he should be FH's guest, not the coworker's guest, but FH said they wouldn't care. So I said I'd go online to our RSVP page and change the name of the girlfriend out to the other coworker, but FH told me to hold off because apparently the ex-gf said something to the coworker about still wanting to attend but was worried it would be awkward.
What's the etiquette on this? I'm not sure why she would still want to attend when the only reason she was invited was because she was the SO of one of our guests. I've never met this girl, FH has met her once or twice so there's really no connection to her if she's not with his coworker anymore... But we DID address the invitation to both of them by name.
