I'm sending out post card save-the-dates sometime soon. While filling in our addresses, I came across something that I need help with. Several friends and family members have serious significant others that we wish to include on one save-the-date (and eventually invitations). How should I word these? For example, my fiance's cousin (and best man) and his fiancee (to be married after us) live at the same address. Should I address it to Bryan X and Crystal Y? Bryan and Crystal X is technically incorrect since they are not married yet, but I don't want to send two postcards. I also don't want to leave Crystal's name off the save-the-date entirely, because I feel like that makes it look like we are excluding her, which I have no intention of doing. We have at least nine other couples in the same situation, and we don't want to unintentionally offend anyone. Any advice would be much appreciated! Thanks!
