I recently sent out our save-the-dates-one of them was to one of our groomsmen and his longtime girlfriend. The envelope was addressed to both of them and even gave them an extra STD magnet since I had plenty of extras. Recently, they broke up- and it wasn't very clean. I was roommates with the girlfriend for a short while and were close at that time, but that was a few years ago and I haven't talked or hung out with her in a very long time. So honestly, I wouldn't care if she came or not to the wedding. When we invited her it was because she was dating one of the groomsmen. I know it would be awkward if they were both there-especially with dates. Obviously the groomsman will still be invited, but is it possible to back out on her invite w/o being totallly rude? Or should I sent her one anyways and figure she won't attend? Do I include "and guest" for both of them? Help!
