I wanted to get advice about the Bridesmaid Lunch. I had made all the plans for my bridesmaid lunch, I invited my mom, my two bridesmaid, my grandmother, and my aunt, and my FMIL and her sister. My mom, grandmother, bridesmaid, and my aunt have done so much for me over the last year, and I wanted it to be a really special thank you for them. I invited my FMIL as thoughtful gesture and wanted her to bring her sister so she would feel comfortable. My F told me that his mom wants to also invite her daughter in law and niece to the bridesmaid lunch. They are just handing out programs and taking care of the book the day of the wedding. I am glad that they are going to be doing these things, but they haven't been there for me every step of the way. I don't want to invite them, because I feel that is what the rehearsal dinner is for. I feel that my FMIL will be upset about this. What should I do?
