So I read this board all the time, and I followed all the etiquette advice when creating our guest list (significant others invited, no splitting up social units, etc).
Wedding is in December around Christmas, so we are aiming at getting guests their invitations in late October due to the holiday season date. FH has a few cousins in their mid-20s, who at the time of the list creation didn't have boyfriends/girlfriends. However, FMIL mentioned the other night that one of them, Ashley, is "looking for a date" to our wedding.
(Background: FMIL gave me her side of the family's list, and she did not include "and guest" for anyone. My family got 90 invites, her family got 90, and my fiance and I got 90 together. My parents are paying for the entire wedding).
When I told her that they weren't invited with dates, she seemed very confused and told me that as they were single, of course they would bring dates. This would apply to about 6 cousins and one aunt. Ummmm....WHAT? Then she said that if people RSVP no, she would tell them they could bring dates. I really don't want to open that door, because then other families who weren't invited with their children might think it applies to them, etc.
What should I do? I am truly not trying to exclude anyone or their SO, but these people DON'T HAVE SOs, they are just looking for dates! If one of them happens to start a relationship in the next two months, am I obligated to invite them? My parents have been amazingly generous throughout the whole thing, and I really don't want to add people to the list if I can help it.
