Trying to finalize the wedding guestlist. We have a very tight light with the guest list since we have a limit of 180. I would love to invite my co-workers and friends but my question is do I really have to invite their boyfriends or girlfriends. I have never met them nor hung out with them. I'm sure that my single friends will be ok hanging out with our mutual friends. As for the co-workers, they have one another.
