AITA for refusing to let my boyfriend's family take over my wedding?

My (28F) long term boyfriend (30M) and I are getting married. We've been together for 9 years now (high school sweethearts) and we have 2 kids together. <br><br>Before proposing 6 months ago (we're planning to get married Oct 2025), my boyfriend told me that he wanted to talk to his family about our upcoming wedding and that he would like us to do it like a traditional one because of all the family and it would be really memorable to our family, but he agrees to share the costs. I accepted.<br><br>I've always imagined to have a small family wedding with some family and friends and go on a nice vacation for our honeymoon. He said it was too small and our families will never see it because we have a lot of relatives and the vacation will be too boring for a big family so he wants it to be a beach wedding with a big family party but we're still okay with that, I'm mostly excited for our big family party.<br><br>He then said that to make it more memorable, we'll have a traditional wedding ceremony since I come from another religious community. I said that that isn't a problem and we would also celebrate his half of his family because that's where he's mostly close to. <br><br>A few days later, he introduced me to his aunt that would also be the wedding coordinator. I was okay with that and so she started discussing costs and all (we'll cover half- they'll cover half) and she was really nice. Everything went smoothly and I noticed that she focused more on her religious practices and how they are important and traditional and some and if I didn't know, I could easily be mistaken to think that we had the same religion too. I denoted a little weird reaction from her when I mentioned my own religion but still, she was very nice and so we all agreed that 2 days before the wedding, we'll have an early anniversary ceremony and a blessing then we'll have the wedding in 2 days and the party, all with his family's blessing. <br><br>It went smoothly and well, well, until a month later my boyfriend told me that his families want to change our anniversary ceremony from a Christian ceremony to a Catholic one. I asked why and he said that it's because his family thinks that the Christian ceremony would "tarnish" their religion. I said that's not okay and that my family will also feel bad about it because I've been Christian all my life but he said his family wouldn't agree. I told him that I don't agree and it's my own family so I would make the decision for us but he said it was what his family wanted. <br><br>Me and my boyfriend have been arguing about it for days but he still insists on his family having their own way. I got so fed up that I said "fine" but the truth is, I don't agree and I told him that it's not okay to change a ceremony that's about OUR family because of his own family's superstitions. I still think about it every day because I don't feel comfortable with it and I don't want to make a scene in front of his family because we are getting married and we have a big family party. I decided to tell my family because I don't want them to be caught by surprise and they were absolutely livid. His parents were also livid when they found out that I told them. They said that I shouldn't listen to my family and that I should listen to my husband. I told them that my husband was being selfish and only cares about his own family and that I won't listen to him. His family said that I should apologize and I didn't. <br><br>AITA?
