Short story:
21+ wedding only.
I thought my cousin was 21 when I told him to save the date / asked for his address.
Turns out he's 20 until two months after the wedding
I had to choose to not invite him despite initiating invitation protocol or make a single exception to the 21+ rule (I'd say there are at least 20+ kids and teens who are either children of friends, children of cousins, or cousins themselves who are still not 21).
Mom begged me to uninvite. I still sent the invitation because I wanted him there and thought it the less rude option. Whoops.
Now, I've got his father mad at me because I invited his 20 year old son (and his 27 year old son and 22 year old step-son) but not his 13-year old son (who he wrote in on the RSVP card and I had to call and tell him no).
And now my FI's grandmother who RSVP'd yes decided she doesn't want to come (she's never flown before and I think she's scared). They already bought her a non-refundable plane ticket and have tried to fill the seat with someone else coming to the wedding but they couldn't find anyone. So now my FMIL told my FI who told me that his aunt wants to bring her 18-year old daughter on the plane in his GM's stead. She was not invited.
So now what? While it might have been unwise to invite the 20-year old, he was the only one on that side of the family and chances are no one else would know he wasn't 21. But a HUGE chunk of family will know that this girl isn't 21 and I'm worried it will cause bad blood.
FI was perfectly ok with with my inviting the 20-year old cousin. But now I worry, that despite his not saying so, he thinks if I get an exception, he should too.
Now it's looking like 20 year old cousin may not even come due to drama with his dad, so I'm thinking I'll tell FI's aunt that no one under 21 is coming to the reception, sorry. I'll mention that she's still welcome to come to the rehearsal dinner and the ceremony. I'll offer to pay for the ticket if she'd rather not.
Then I think GM might change her mind and decide to come. I'm really hoping so. She's my FI's only living grandparent and he was really excited she was coming.
Thoughts? Anyway for me to get out of this without messing things up more?
