So I'm not sure how to address this invite.
I have a guest who is engaged, but they don't live together. It feels weird to address the invite with both their names but only mailing it to her, but then again it also feels rude to address it to "Jane Doe" and Guest when they are clearly engaged.
So would you do
Miss Jane Doe and Guest
or
Miss Jane Done
Mr. John Smith
Either way "jane doe" is my guest, so it will get mailed to her.
