so my original plan was to only allow a guest for singletons that were in serious committed relationships. That has not been a problem at all so far and most of my young single friends understand. Well... (background info) My great uncle's wife passed away last fall, maybe september/october. Well I had heard several months ago that he was "seeing" his dead wife's sister. Today, I get his RSVP back and it is for TWO people. I probably won't say anything but... as my grandmother would say, Gawd... I hope this won't cause any family drama at my wedding if he shows up with his former SIL. Who knows, maybe is kids are aware and Ok with it... just seems weird to me.
