So, FH casually mentioned last night that one of his friends said she "might bring someone" to the wedding. He didn't say no, we're not doing plus ones, even though I made clear to him that that was the plan. Sigh. So now I suppose Friend A gets a plus one. He has a couple other single friends coming too. Do we need to extend plus ones to everyone now? FH says no, but for me as a single person at a wedding, I'd be ticked to see someone else able to bring a friend/date, when I didn't get that option. I think Friends B, C, etc, now need plus ones too, to be fair to all. (My budget be damned, apparently.)
What do you think? What's the etiquette on this?
