Originally, my FI and I were having one person each, not out of any planning just because both of us could quickly and clearly imagine the bridesmaid/groomsman that we wanted to be with us. For him it is his best friend (and my brother- side note: you know a guy is a good catch when you introduce him to your brother and they become best friends). For me it was my sister. My sister has a lot of issues with being in public and having her photo taken (my second post was about this issue, she didn't want to be photographed and I wasn't sure how to accommodate her).
After being in the bridal party for my older sister's wedding a few weeks ago, my younger sister (BM) realized that it was too much stress and we realized that she would be happier if she could just attend my wedding without having to worry about standing up in front of everyone or having the photographer take too many pictures of her. As a guest, it will be much easier for her to avoid the camera, and she says she will try to be in two photos- a large family photo and a photo of just the two of us. I am a little sad that she won't be standing next to me when I get married but we made the decision that is best for her health and happiness.
So I mentioned this to my FI and he gets all disappointed and quiet. When I ask him whats wrong, he admits that he told one of his friends that the reason the friend couldn't be a groomsman was because I was only having one BM and didn't want uneven sides. Now I never said this, he just didn't know what to do when the guy excitedly said "Can't wait to be your GM" so he made something up. For a second FI asked if I would pick someone else to replace my sister but I am pretty sure my long dead stare scared that idea right out of him.
