My shower is next Saturday and almost all of my FMIL's guests did not RSVP. Since my mom doesn't know them, my FMIL started to call and email. As soon as she did, almost all of them said they couldn't come. She got very upset because she atteneded all of their showers, weddings etc...Today she told me she wanted to take a few of them off the wedding guest list. I don't mind, I'm all for the free spaces on the guest list, however, I've already sent these women save the dates and they were all invited to the shower. I would be furious if I was invited to the shower and not the wedding. Now my question is, do I stick to proper wedding etiquette and keep them on the list or do I respect my FMIL's wishes and remove them. If it helps any, neither myself nor my FI know any of them....
