We are having a small ceremony followed by a lunch, with a larger cocktail party later for more people. We originally decided to invite just aunts and uncles and a few close friends to the actual ceremony. But, I am very close with my cousins, so after talking it over we decided to invite them too. The invitations have been sent out, and those who have been invited to the ceremony received an added invite to that portion. My fiancés cousin sent him an email today curious if she could bring her kids to the wedding/lunch portion. The thing is, we didn't even invite her to the wedding itself, only the cocktail party. She is wonderful, and one of the cousins he has more of a relationship with, but if we invite her, we'll have to invite her brother and his wife, and the rest of his cousins... Which we honestly do not have room for, nor can we afford. This cousin and her family have temporarily moved in with her parents, my fiancés aunt and uncle, whom have been invited to the ceremony so she must have seen our ceremony invite and assumed we forgot to include one for her. How do we explain she's not invited to the ceremony?
