AITA for not sharing my wedding photos?

My fiance (m35) and I (f35) are getting married in a month. We are having a small wedding with 35 people - parents, siblings and their spouses, and a few close friends. My parents are footing the bill and we've had to make quite a few compromises to make them happy. I wanted a wedding on a beach, but my parents wanted it in a church. We wanted live music, they wanted a DJ. We wanted a heavy metal theme, they wanted traditional wedding decorations and attire.<br><br>The final straw was when my dad said that my mother would be incredibly upset if I didn't wear her wedding dress. I'm 5'8 and 135 lbs, my mother was 5'2 and 80 lbs when she got married. I can't fit into her dress, I can only hold it up. I told my parents that I couldn't wear it and when my mother started crying, my dad offered a compromise: My mother would get the dress altered for me.<br><br>I don't want the dress altered, I don't want to wear the dress at all, and I have told them this. My mother is quite stubborn and has now paid to have the dress altered without asking me for my measurements (apparently, she went back to her wedding album and gave the seamstress her measurements from 27 years ago, when I was 8). I am a little bigger now than I was at 8, so the dress doesn't fit me at all. It's a little tight in the waist, short in the hem, and the bodice is a little loose. I am quite angry that they went behind my back to make alterations to a dress I have no intention of wearing, and told them that we could no longer afford to make changes just because they wanted them. My parents got very angry and told me that if I didn't wear her dress, my mother would tell everyone at the wedding how ungrateful I am and to never speak to me again.<br><br>After her outburst, I realized that I didn't want to get married in front of my toxic mother. I told my fiance and my sister and they were both on the same page. We decided to get married at the courthouse this afternoon and the wedding will now be a reception. I spent the afternoon with my fiance and my sister and her husband and we went for dinner afterwards. It was worth it to get my mother out of my hair and we all had a good time.<br><br>My mother called me at 10:00 and asked me what I had planned to wear to the wedding. I told her that I already wore my wedding dress that day and she asked me what I meant. I told her that I didn't want to get married in front of her and that I had gotten married that afternoon and she basically lost it. She called me horrible names and hung up on me.<br><br>My parents have basically disowned me and I'm not too worried about it. What I am worried about is that when I post my wedding photos on social media, my family will see them and lose it. I have decided not to put up any wedding photos on social media at all. My mother is friends with some of my friends and I don't want them to see the photos and tell her, I don't want her anywhere near my life for the foreseeable future.<br><br>My sister thinks that this is a bad idea because she won't have any photos from a wedding. My fiance thinks that it's not worth the risk of my mother finding out too soon. AITA for not wanting to post my photos?<br><br>Edit: Thank you for your comments and awards. My honeymoon ends on Sunday, so I will get back to everyone then.<br><br>Edit 2: I just got back from my honeymoon and have taken the time to read most of the comments. Thank you all very much for your kindness and support. I am not allowed to post photos of my wedding dress, so I have posted photos of my reception dress on social media and have gotten a lot of positive comments. <br><br>My mother is still ignoring me, although I received a very nasty message from my grandma (who speaks very little English). My sister has not told our parents that she was with us when we filed for the marriage license and got married. She has posted photos from the reception and she has given me copies of the wedding photos.<br><br>My husband (hehe) and I are well. We are settling into our new routine and are enjoying our time together. <br><br>And for those of you who live near a Five Guys, get the milkshake.
