We received the STD last winter and the wedding was at the end of September. We never got the invitation and so I assumed we were no longer invited to the wedding. The groom sent me a fb message asking how my spouse and me are doing. I replied and said how pretty the wedding pictures were that I had seen. He responded saying he wished we could have made it to the wedding. How do I reply to that?? If we were invited wouldn't they have asked us why we hadn't RSVP'd before the wedding? This is a really awkward situation now.....advice anyone?
