My sister, who is my best friend, is getting married in less than a month. Our mother has previously said her "fiance" (she and our father got divorced 2 years ago) isnt coming to the wedding which was a relief for us. A week ago she says he now wants to come. This man has met us once and never came to any of the showers or other family events. Long story short, my mother says she will not go without him and thus is no longer coming to my sisters wedding. My sister and I are devastated to be thrown aside, but i really want to make this day special for my sister. Does anyone have any suggestions on how to make the day even more special or if there was something i could do so she doesnt have to think about the abandonment of our mother?
