I want my bff of 27 years (our moms were pregnant together, so we've been friends since we could crawl) to be my MOH, but here's the thing. She is not reliable and she likes to back out of things at the last minute. I have not asked her to be my MOH yet, idk what I am waiting for. I know she will say yes but its the day of my wedding I am worried about. If she backs out at any time, not just last minute I will be VERY PISSED!!!! And I think that would be the end of our friendship. I have made my sister my Matron of Honor as a back up plan but if my bff backs out...idk I really think it would be the end of our 27yr friendship. Am I being ridiculous? I also do not want to offend her by not asking her to be in it.
I can always tell my BFF how I feel I just don't know how to say it without hurting her feelings. I don't want to be like "well you're not reliable so Imma make you a BMs instead of my MOH, that way you don't screw me over" how can I say it wi/out being harsh?
