My FMIL threw me a surprise shower over the weekend with all of the members of her family, many of whom I've never met before. Tonight as I started writing thank you notes, I realized that her aunt who was at the shower and gave me a gift was not invited to the wedding!
I feel terribly rude, but I obviously didn't have anything to do with the guest list. Should I send her an invitation now, even though the wedding is only 3 weeks away?
Help!!
