So I have two MOH's.....my best friend and my sister. My sister and I don't always get along so I have the two of them sharing duties. My bf has really gone out of her way to plan my shower, bachelorette party, and just to make sure that everything in general runs smoothly. I'm just not sure who to have stand next to me during the wedding. I know that both of them want to....my sister will throw a fit if she isn't picked. I know my bf won't complain but she probably deserves it more. Not sure what to do. Suggestions?
