In the beginning, we were planning a medium sized wedding. FMIL hosted a very informal engagement party a year and a half before our wedding date (facebook invites, BYOB (if I would have known, I would have not accepted the party)). Our friends, 40 or so, were invited and it was not a gift giving event.
After much stress and unhappiness, we have decided we would prefer a very intimate family only wedding instead. Around 15 people total. Is there any way to make this okay as I know all people invited to prewedding events must be invited to the wedding.
