So....growing up, until we were teenagers, my sister and I were relatively close...then once I got my first job at 17 (she was 15) I started getting friends and she got her own friends and we kinda grew apart. Now we are complete opposites. I still love her because, well she's my sister, and we have so much history, but just being around her for more than 30 minutes and usually something she does annoys the hell outta me.
I was trying really hard to work on our relationship after 2 years of just not trying at all, and so I made mention of her being my MOH the day after I got engaged, since then I had one phone conversation with her when I said that I didn't care what my fiance said she could still be in the wedding and my MOH (long story there but basically she did something which really pissed him off, I think he overreacted not wanting her in the wedding anymore, but she definitely was in the wrong also). So she thinks its a set done deal, but I've been trying to plan everything and think about things, and I realize that when I'm thinking about planning girls days to visit venues or bridal shows or looking at dresses, I would almost always choose some of my friends to invite over her. She means well, and she's really good at planning/organizing things, but only on her time schedule. She is very, very dramatic, and always tries for the shock value (over the top, risque clothing, bright makeup, hooker heels etc.) while I am 100% opposite in style. I think she would be able to put aside her styles to help me plan for what I like, but I'm worried about the drama, we always seem to get in fights if we're around each other for more than an hour interacting, and I'm going to have to spend entire days with her! I would be totally fine with her being a BM alone, but is it wrong of me to want to reserve the MOH position for, well someone I would feel more comfortable with?
I should also mention that the last time we actually talked, she said that she didn't think my FI and I should get married. So I also don't want my MOH to not like my FI. I should also say that my FI and I have been together for 2.5 years, and the rest of my family loves him, so it's not that I am marrying an unlikeable asshole.
