One of the biggest reasons I'm holding off starting to plan our wedding, is the wedding party, specifically my MOH. For years, I always pictured my best friend next to me. Granted that person has changed over the years, but people change and grow over time. After we got engaged, I was all but about to ask her, and my mom stopped me, bland made the comment that if I didn't ask my sister to be MOH, she would be really upset (my family holds grudges). My sister and I have never been that close. She currently lives with my fiancé and myself, but it's driving us all nuts. Sometimes, my fiancé even has troubling being around her. I've always pictured my MOH being that person who knows me best, who would know when I'm being bridezilla and who would help me make the perfect day. Someone who is close with my fiancé as well. That person is my best friend. I know it's my decision, I just don't know what to do without everyone getting upset. Advice??
