AITA for telling my family that my sister strongly implied that she doesn’t want me at her wedding, causing most of them to RSVP no?

My sister and I have always had a complex relationship and are very different from one another but I do love her and only want her to be happy. She got engaged a few months ago and at the beginning of last month she called me and told me that they’re going to have the wedding in Alberta since his whole family is there, then she said that she wants me there but would “totally understand” if I didn’t come since I don’t fly and it’s a 3-4 day drive, at that moment I didn’t realize she was telling me not to come so I told that I wouldn’t miss it for the world, that I would drive with our cousin and make a road trip out of it.

Last Thursday I got my invitation and when I called to RSVP I asked about the dress code, since my dad told me that she emailed him about a certain color suit and tie so they could coordinate the pictures. She told me that I didn’t have to worry about that, that it’s nothing personal but because I have stretched ears, piercings and a tattoo on my hand, I don’t fit the aesthetic they’re going for, so if I come we’ll take pictures with just us but I won’t be in THE pictures. I don’t cry often but that made me cry and I told her that if she doesn’t want me there I won’t go, she didn’t say anything and we hung up.

On Friday I had lunch with my grandparents and my uncle and told them about it, my grandmother got so upset that she started crying and told me that if I’m not welcome neither are my grandparents. My aunt and her husband and all my cousins RSVP’d no as well and my brother and parents are thinking about not going as well. Although it means the world that they love me so much I feel awful, like I’ve ruined my sister’s wedding, that I should’ve kept my mouth shut.
