My MOH is my sister and as much as I love her, I am well aware of her faults. She has a hard time holding down a job and has money problems more often than not. I let my BMs pick their own dresses, shoes and accessories so they could determine their own budget. The first time my sister complained I told her she didn't have to be in the wedding party and told her to take a few days to think about it. She came back and told me she did want to be in the wedding. She's already ordered her dress and I don't want to take her out of the wedding, but the complaining is really getting old. She even complained to other relatives about it at my bridal shower. Any advice?
