My wedding is over and done with (it was perfect) and while this no longer matters, I am curious on how to handle this situation.
We had a smallish wedding of 75 people. I call it a destination wedding because everyone travelled to a specific location (shortest drive for anyone was 8 hours) including us.
I invited a friend and her fiancé. She RSVP'd for herself and a friend I have never met. Call me crazy, but I think it is rude to switch your fiancé for your uninvited friend. It was a smallish family and close friends only wedding and I hated thinking someone I have never met would be there for this intimate moment. Call me what you will, but that's how I felt. I ended up just ignoring it and letting her come. It wasn't the end of the world of course and I didn't really even think about it on that day.
Like I said, it's over and no longer matters, but maybe a future bride has this issue and wants to know what her options are. Did I do the right thing? What else could I have done?
