I'm in a similar situation...find out how you FI feels before you react.....Are you having an AHR..if so I'm sure they will participate in that. We are not having an AHR..and at this point who ever comes with us comes. Who ever can't make it is ok too. This is a day that symbolized my life with my FI. When we are at home alone....none of those people will be there. I hope that helps
