My (F24) best friend (F23) is getting married and I'm part of the bridal party. I found out that one of her bridesmaids is someone I've never forgiven for bullying me when I was a child and I don't know what to do.

I was pretty devastated when I first found out and I just wanted to get out of the relationship. Then I took some time to think it over and I decided that I should talk to this person. I texted her and we decided to meet up for a cup of coffee for a talk. I told her that I had never forgiven her for what she did to me and I simply don't want anything to do with her. I asked her not to respond to that message so that my best friend wouldn't find out that we were talking. We met up and she apologized and said that she wanted to be friends with me because she felt guilty for what she did in the past. She said that I seemed like a really nice person and she thought that maybe we could fix things between us and we could be friends, maybe. I told her that I didn't want to be friends and I didn't want to have anything to do with her at all. She apologized again and I left. <br><br>After that, I felt better because I was confident that she wouldn't contact me again. Then the other day, I received a message from my best friend inviting me over to her house. I went and when I got there I found out that the other bridesmaids were also there. I asked what we were doing and she said that we were going to have a movie night together. I wanted to leave but it was already too late and she had already made all the arrangements. When the others got there, I realized that this was premeditated and I started to feel that something was wrong. My friend came up to me and we started talking and I found out that this person had talked to her about our meeting and the fact that I didn't want to be friends with her and stuff. I was angry as hell and I told her that I wanted to go home but she begged me to stay for a bit, to not ruin the night. I stayed and this person was staring at me the whole time. I didn't say a word to her but she didn't talk to anyone else either. I wanted to go home but my best friend kept me there until it was too late.<br><br>After that, we started hanging out more often and this person would join as well. I didn't talk to her and she didn't talk to me either but it felt like she was there just for me. Then this day, we were all at this bar when my friend got up to go to the bathroom. I followed her and when we were alone she told me that this person had begged her to let her be a bridesmaid and she didn't want to hurt her so she said yes. I asked her if she cared that I didn't want to have anything to do with her and she said that she cared but she really wanted to make this person happy and then she said that I was the best friend and the maid of honor and she loved me but she couldn't make me happy this time. I didn't say anything and we went back to the others. This person noticed that we had been talking and she looked upset.<br><br>I would like some advice on this. I don't know what to do and I don't want to ruin the relationship I have with my best friend. I feel like this person is bothering me on purpose and I want it to stop. I feel that I can't go anywhere without her and it's very annoying.<br><br>Tl;dr!: My best friend is getting married and I found out that one of her bridesmaids is someone I've never forgiven for bullying me when I was a kid. I talked to her and told her that I don't want to have anything to do with her and she got upset. Then my best friend wanted to have some girls nights and this person would join as well although I didn't talk to her. I feel like she's bothering me on purpose and I don't want her there and I don't know what to do.
