So, one of my BM sent me an email last week, explaining that even though she knew it was probably going to come off wrong, she didn't feel right being in my bridal party. She said that she felt we had grown apart in the past couple years and it didn't seem right, but that if I really wanted her, she'd do it for me.
It's true that we're not as close as we once were, and I imagine that she doesn't feel all that comfortable with the rest of the girls, since she doesn't live near us and doesn't spend time with us. Also, her younger sister just got married in early Dec., and is having a baby this month, and, a mutual friend of ours, who I'm also not as close as I once was with, got engaged and asked her to be the MOH.
I didn't want to be mean or insensitive, so I told her that I completely understood, and relieved her as a BM. I'm not replacing her as a BM (even though I've purchased a lot of gifts for them, many of them personalized), and on more than one occasion I had thought I had made a mistake by having a large bridal party, but now... I guess part of me thinks she wanted out so she can dedicate herself to being this other girls MOH

I guess there really isn't any advise to give me, just wanted to vent a little. Lol. Thanks ladies!
