So, my sister is my MOH and she has done nothing to help with the wedding. My other bridesmaids have told me she has even complained about the money she spent for the dress! ($170.00)They threw my bridal shower and my sister/MOH brought pulled bbq chicken and let me know that was also her shower contribution and gift! She even left early and wanted to take her leftovers with her!! She asked to drop out of the wedding last month because she is getting minor surgery and will have a small scar that will be visible. I feel like she just doesn't want to be in the wedding. Our wedding is 19 days away, should I just tell her not to participate since her heart isn't into it?
