It looks like one of my bridesmaids will probably be breaking up with her boyfriend before my wedding (which is ~1 month away). She told me (rather than asked) the other day she's planning on bringing a friend who is a girl as her +1 instead. I've only met this friend once or twice in passing.
All of the wedding party got +1s regardless of their relationship status - but at the time the invites went out, 8 of the 10 in the party had significant others. The rest of our wedding guests only got +1s if they were in a long-term relationship.
Am I crazy for not really being OK with her bringing a random girl as her +1?
