Hi everyone! A couple I invited to our wedding originally RSVP'd yes. The RSVP deadline was March 10th. We're getting married on April 20th. After the deadline they told my mom that their son who is stationed in Germany was getting vacation that week so they wouldn't be able to attend the wedding after all, but not to tell me. Needless to say, she told me. I then received a card and check from them saying they were sorry but they couldn't attend due to their son's vacation. We have fewer guests going to our wedding so we upgraded our package which is $25 more per person. Earlier this week the husband RSVP'd on a Facebook page I made for the wedding to keep guests updated. He never said anything, just clicked "yes", even though I had said on the page that I'm not counting Facebook RSVPs. I talked to my mom earlier today and she said that his wife said their son's vacation was postponed so they cancelled their trip and now they can go to the wedding, but she's embarrassed to tell me. I really don't like the way they've handled this. I don't know why they can't tell me anything directly. What should I do? I already turned in the seating chart but technically I can change the guest count, it's just that now it would cost more due to the upgrade.
