Our invites are out and we're getting back RSVPS. Our plan was to allow anyone in a relationship of any kind to bring their BF/GF/spouse. Anyone not in a relationship we did not write "and guest" on their invite (for those in relationships, we included the guest's name on the invite). Still, we've recieved a few single people RSVPing for 2! Ugh. Where did we go wrong in our addressing? Or did we? I mean it's too late now to change anything, but I'm just curious how to politely say "do not bring a stranger to my wedding" haha
