I had gotten along great with my fiance's sister until we announced our engagement. When he called to tell her she hung up on him! We picked the wedding party 2 months ago. His sister realized 3 days ago she was not a bridesmaid and has been terrible ever since! Their mother passed away in February so it has been a difficult year. The sister has called my fiance 112 times in the last 24 hours to either yell at him or hang up on him. We offered to have her light the unity candle at the ceremony (in place of their deceased mother) and to also do a reading. She refused both! I don't think I am wrong in not having her in the wedding party (she is full of drama & the wedding party is so small my own sister is not even in it!) What can I do to try and smooth this over. I don't want it to cause major problems at Thanksgiving and beyond.....
