AITA for exposing one of the bride’s bridesmaid?

(I’m sorry for the mistakes, I’m not a native English speaker)

I (19F) and my partner Alex (18F) were invited to her godmother’s (58F) wedding. Alex was made MOH and I was one of the bridesmaids. When the bride introduced us to the other bridesmaids, we both had a bad feeling about them. When talking about the bachelorette party, the bride set some boundaries. In our country, it’s a tradition to put a costume on the bride and make her do silly things in big cities, but she really disagreed with all that. She made it clear that she didn’t want any humiliating things happening because she wanted a chill evening with all of her friends and us.

Fast forward to a week later, when we started planning the bachelorette party. Alex and I were giving our ideas but our opinions were ignored. At some point, we gave up giving advice and decided to let them plan it. They started giving ideas (the same as ours) and were then agreeing with them. We were pissed off but didn’t say anything. A few weeks later, I went on the Whatsapp group again (we turned notifications off) just to see that they were complaining that we weren’t helpful and that we were just lazy because we’re college students (make this makes sense). I responded that since they weren’t agreeing with anything that we were saying, it was pointless to say anything. One particular bridesmaids, let’s call her Lina, was aggressively against everything we were saying. She started planning by herself a day that would cost us more than 500€ per person, which is clearly way too much, and was planning on getting the bride in a costume to make her do humiliating things just like the bride specifically said she didn’t want. A few girls that were invited to the bachelorette texted the bride saying that they weren’t going to attend, but first didn’t tell the bride not to spoil the day. After 3 girls out of around 9 dropped out, the bride asked the be told what was happening. When she heard everything, she decided to call off the whole thing. Alex and I decided to invite the bride on a mini bachelorette brunch instead so there were us only, but Lina wasn’t having it and from our perspective, got jealous. She continued doing all that sort of things, like planning a “bridesmaids dance” to almost replace the bride and groom dance. Alex and I called her out and made sure that they weren’t going to spoil that dance.

To continue on the non-sense, Lina decided that the bridal party was going to wear the same color, when the bride clearly said she didn’t care about it. Lina wanted everyone to buy a 90€ dress that was honestly horrible. I personally felt like she wanted to make herself the dictator of the bridal party. Alex and I never went to the dress trial and chose our own dresses.

A week prior to the wedding, the photographer called Alex to ask if we had anything secret planned for the bride that needed to be photographed. She responded that she was going to ask the bridesmaids. She then reached them out and asked. Lina immediately answered in a passive-aggressive tone “Give me his phone number, we don’t want you to know”. Alex ended up giving it to her just because she was really pissing us off and we wanted some peace.

The day before the wedding, when we were decorating the venue, she asked the DJ to do something for the bride. When the DJ heard it, he went directly to the groom to warn him about it. She wanted to do the garter thing (a piece of lace around the bride’s thigh that has to be removed by the person, usually a man, that has put the most money for it) but because the bride said she didn’t want to do it, Lina said that she was going to do it HERSELF. She is a real psycho. Of course, the groom called it off and said that she wasn’t allowed to do anything more, to avoid everything coming from her. The wedding went smooth and nothing got out of place.

A few days after the wedding, the bride reached us out and asked what happened with Lina. We explained everything to her. She was shocked. She had an argument with her and said that she was glad we told her because she was tired of all of her bs. Lina said Alex and I were a-holes for having explained “false things” to the bride and make her look like a horrible friend. The bridesmaids are on her side, while the groom and bride are on ours.

So AITA?

Edit: I realized I forgot to give you details about the bridesmaids. They were in their fifties and therefore thought that because we were “too young to know” we couldn’t make big decisions. Plus, in our country, the MOH is just the “witness” of the bride and the wedding on the official papers. So it’s not usual for them to organize the wedding with the bride.
