I found out in the past week that three of our friends have broken up with their long-term SOs. I was looking through our invitations last night before popping them in the mail this weekend, and all of those people's SOs are listed on their invitations. Do I address new ones? I don't want to seem insensitive by keeping them on there, or rude by uninviting them if they happen to get back together (not unusual for one couple). Suggestions?
