I have 3 sisters, none of whom I'm particularly close with, and a best friend of 16 years who is more or less just part of the family (our families do everything together), that I would like to include in the wedding party. I would really like to ask my best friend to be my MOH, but I feel like it would be really bad form to not ask my older sister (there's 7 years between us).
When my fiancee and I got engaged she reacted really badly, making faces and all that, and it really hurt my feelings. I also know that she doesn't really like my fiancee. On top of that, she's told me that if her and her boyfriend ever get married they would go to a beach somewhere tropical with 2 of their friends and get married. However, even after all of this she still expects me to ask her to be my MOH!
My mother thinks I should just chose my sister and suck it up, but I'm not so sure, and I really don't know what to do.
Any advice, or anecdotes, or suggestions would be very helpful.
