My FI and I are trying to decide what to do for a WP. While I am not a huge fan of the whole bridal party thing, I am not against it. We have both agreed to have one close friend and our siblings in the WP. I only have one brother while my FI is one of 4. He has said he doesn't mind keeping the WP small but would choose his brothers to be his GM. While I really want my brother to be included and my FI has said he would love to have my brother be a GM, he would also like it if I asked his sister to be a BM.
Here is the problem. While I understand that I could have my brother stand on my side and his sister stand on his side, his sister is a chronic complainer and wouldn't want that. She was a BM in her other brother's wedding and criticized EVERYTHING that the bride chose - dress color, hair style, nail polish, shower, bachelorette party, having to take photos before the ceremony - literally everything about the wedding. Both my FI and I are pretty understanding that this is just how she is, but I do not want that kind of negativity surrounding me during my special (and most likely already stressful) day. Despite the fact that we were never really close, I honestly would not mind having her as a BM, the fact that I know she's going to complain about everything I do is really bothersome. I just feel like no matter what happens - if she stands on my side or her brother's she's going to have a problem. I want to honor my FI's wishes but I don't know how to say that it makes me uncomfortable to have her in such an intimate roll, especially when my MOH is the only other lady I'm going to have in the WP.
