First time posting a thread... I have a question about invites to friends who are in rocky relationships but live with their SO. For example, we have a friend with an on-again/off-again girlfriend who we've met multiple times, and they're currently living together. We want to invite the friend plus one because all of our guests are getting plus ones, but we don't want to invite the girlfriend by name in case they break up again. Is that considered rude?
