I am not quite sure what to do. My friend and I are both getting married next summer. My wedding is about a month before hers. We've been friends since high school and since I got engaged our friendship has been rocky. She was upset with me about having my wedding so close to hers which caused a fight between us especially when she asked me to change my date. She has been really mean and bridezilla like to me and a lot of other people since she started planning her wedding. My FI and I are in her wedding party and right now just her FI is in ours. I have not put her in my wedding party because I feel that she will stress me out more than I need to be and she hasn't really been supportive or much of a friend since I got engaged.
We haven't talk or really seen much of each other in over a month despite my attempts at trying to get all of us to hang out. We met up the other day to talk and she is giving me a week to decide whether I want to stay in her wedding party. Her and her FI feel that the way to save the friendships would be either for all of us to be in each others weddings or to just have 2 meaning one in ours and one in theirs. I am not sure what I want to do here. I want to be supportive and be their for her on her big day but at the same time with the way our friendship has been I am not sure I could do that. I feel that if I do drop out she would be hurt or offended by that. I am also worried that it will affect both our FI's friendship because they have been friends for a while. So any advice would be helpful.
