I have a few bridesmaids I am absolutely sure about having in my wedding party - my sister, and three of my best friends who have been in my life for years. However, there is one girl I am so on the fence about. On one hand, I have known her for over five years and she has been one of my fiance's best friends for more than eight years, because she is married to my fiance's best friend (and soon to be best man of our wedding. my fiance was also the best man in their wedding). I really get along with her for the most part and we are similar in many ways. I do consider her a good friend. On the other hand, she used to be passive-aggressive with me in high school when I first came into their lives for the first few years until she was further in college after her own wedding, so I never knew for a long time if she actually liked me or not. She purposely left me out of her wedding in every way possible to make sure I wasn't included, WHICH I TOTALLY GET because it was her wedding and what they wanted - it's everything else about it that I won't go into here because it's so much little stuff. She also talks shit about everyone else's weddings that we have been to together, or people we don't know, and it's about anything and everything - paying for her own hair and makeup and not being able to do her own makeup for other people's weddings she's in, bridesmaid dresses she doesn't like or it's not quality enough, complaining about the people in the wedding, needing to just get drunk to get through them- it goes on. and I'm honestly afraid that if I were to ask her to be in ours, she would do this to me behind my back and I used to try so hard to get her to like me, that I worry it's all I'm going to focus on if she were in our wedding and take her opinions to heart more than what my fiance and I really want. But we also both know that we will all be in each other's lives for a very long time, since we all 4 of us are really good friends and hang out pretty often. I just need some unbiased opinions here - what would you do? what else should I maybe consider that I'm not already when it comes to whether I should ask her or not? Please, no judging, and help!!!
