So my fiance and I are stumped on this one.
We're trying to narrow down our invite list to reduce our guest number to help cut costs and get a more accurate number to help with narrowing down our venue choices. We both have a few co-workers we'd like to invite, but some of them have partners we've never met before. Would it be strange to only send an invite to a co-worker who is married without inviting their spouse? We aren't offering a plus one for all of our invitations, even to friends so I would hope it wouldn't be too strange but between me and my fiance, we don't know if this would be considered rude even to a more modern crowd.
