AITA for bringing my boyfriend to my friend’s wedding?

My friend (28f) is getting married. I (26f) am not remotely close to her; her and her fiancé (29m) are friends with some of my friends. My friend and I were friendly, but the friendship never really grew beyond that. I don’t know a lot about her and she doesn’t know a lot about me. That being said, we have always been on good terms.<br><br>She messaged asking me to be a bridesmaid. I felt a little awkward about it, since I don’t really know her/anyone else involved very well, but I also don’t want to be an asshole. I also didn’t want to say yes and then back out because I don’t want to be “that girl.” So, I told her I’m honored that she offered me that role and asked if she thought it would be okay with her fiancé. She said it was entirely her idea and that she’d text her fiancé to let him know. A few hours later she told me that her fiancé was fine with it.<br><br>I’m not sure why, but her text made me feel strange. I decided to text her fiancé and thank him and let him know that I’m really excited about it. He said that he was a bit surprised by her asking me, since I’m not in their friend group, but that he had zero issues with me being involved.<br><br>Then, I got a text from her bridal party group chat that said the plan is for all the men to stay in the venue’s hotel with the women for the night before the wedding. I texted the groom and asked if he had a problem with my boyfriend staying if he comes with. He said he wasn’t totally comfortable with that and I completely understood. I told my friend and she said she was also not comfortable and that it was supposed to be a girl’s night anyway. I completely understood and was fine with it.<br><br>The problem came when my boyfriend asked if I could get off work the day before the wedding so we could drive up together. I asked my friend and she said she really needed me to help set up and run some errands. I asked my boyfriend if he could come alone and he said no. He has to work the morning before and it’s a 5 hour drive there, so he won’t be able to make it in time. I asked my friend again and she felt REALLY strongly against my boyfriend coming. She said she didn’t want him and her fiancé to be there and she only asked me because it felt rude not to (which I understood) but now she feels like I’m taking advantage of her generosity. I got really confused and asked if she was okay with him coming to the wedding or not. She said that she’s fine with that.<br><br>I was really confused by that so I texted the groom and asked what the plan for the guys are. He said that the guys are staying at the hotel. I asked why he didn’t tell me when I asked. He said it didn’t occur to him and that he felt a little weird telling me their business. I told him that I think his bride might be pregnant and he laughed. I said it felt like that because she didn’t want us both there, but if I didn’t come, I would be there for the wedding and he would be there for the night before. He agreed and said he’d look into it and get back to me. He did a day later and said that they originally planned for both to happen, but she later decided she only wanted the girls the night before and the guys were still going to stay. He said he thinks she changed her mind because she wanted to make me feel bad for bringing my boyfriend. He apologized and said that she was in the wrong. He said it doesn’t matter either way because they already ordered the decorations and it’s too late to change anything anyway.<br><br>I feel like this is my fault. I feel like I did something wrong by telling him. I don’t know. I just feel really weird about the whole thing. Am I here?<br><br>TL;DR: I’m a bridesmaid for a woman I’m not close to. She doesn’t want my boyfriend to come until the reception. He was only coming if he could stay the night before. She was originally going to have the guys stay but now isn’t and I feel like I ruined something. AITA?
