So, I had all my bridesmaids picked out, I've been getting everything ready for the girls that I chose who I knew would be there for me and the most supportive of me at this time in my life with my maid of honor being my older step sister who has always been there for me. My family, however, are telling me that if I have my step-sister be my maid of honor, I should at least have my sister be one of my bridesmaids. She has been invited to my wedding, contrary to what my fiance has asked, but I absolutely want her to have nothing to do with my bridal party. To put things in perspective, she and I have never had a good relationship with her bullying me at school, stealing boyfriends, the usual sister stuff. I've learned to forgive and forget. She decided, after I announced my engagement, that she wanted to get married. I tried to help her and helped even give her money for vendors she said she was getting for the wedding and even pitched in to help buy a dress for her. After a few months of trying to help her with her wedding, I find out that she had already gotten married, not telling anyone in my family until her husbands family sent her congratulatory cards and calls and my parents called me up, upset that she never told us. When I confronted her about it, she decided to get angry with me that I felt I needed to confront her about it and that what she did was her own business. Since then she has moved and not given me her address, has not talked to me via e-mail or phone call and decided to completely block me on facebook. She wasted my time, my money, and cut all ties with me. I have no real way of reaching out to her and we haven't spoken for the past 4 months. She refuses to be over at my parent's houses for the holidays while I'm visiting and seems to want nothing to do with me. I think that even if I did ask her to be a bridesmaid, she wouldn't even show up. Am I in the wrong for not having her as a bridesmaid after what she has done and is currently doing?
