Well, i know I'm not the asshole here but it still makes a good story for this sub. My brother and I were very close growing up, he's two years younger than me. That's probably why everybody called me the grown up and he was viewed as the little kid, even when he turned 20. He started a relationship and moved out of the house asap. After two years he got engaged to his now wife. At the beginning of the relationship he invited me over almost every second weekend. I liked his finacé but always had a feeling she doesn't like me being around and that my brother invited me. So he stopped after six month into the relationship. He didnt answered my calls or texts and everytime i asked him to hang out he would say yea and then cancel lile ten minutes we were supposed to meet. I asked if everythigs good between us and he was like "yeah ofc, just busy with work" so after a while the two of them got engaged. The wedding came around and until then we never met the brides family. At dinner I was the only family member that wasn't seated at the "family table". I was actually seated at the last table with people I never met before. After a while everybody was drunk, partying and dancing at the wedding and my brothers MIL came to talk to me. We went outside and she wanted to know how i liked the party she organized. She was very friendly. After a short smalltalk she leaned over and puked all over my dress (she was only drinking red wine). Her younger daughter (sister of the bride) saw this and started screaming at me "DIDN'T YOU SEE SHE WAS ABOUT TO THROW UP?? WHY WERENT YOU HELPING HER?" I couldnt grasp anything about this situation. I was pissed, but still helped to clean up the mess. After that the sister started insulting me, so i called an uber, went inside to get my stuff and told my brother "I'm gonna leave, thanks for the invite" AS FRIENDLY AS POSSIBLE and he was like "What do you mean? please stay a little longer. Then i told him his MIL puked all over me, opened my jacket and showed him my dress. He didnt react at all, just stood there kinda catatonic and I left. After that I tried to talk to him but he wouldnt react to any calls or messages. I wrote a message telling him I thought it would be appropiate for the MIL to say sorry, I wouldnt be mad or anything, I just wanna put that all behind. In any other situation I would try to make things work but I felt sooo violated. Now I found out that the MIL stated to him that they cannot invite me ever again to any occasion because SHE is so embarrassed. That wouldnt only include me but also our own mother, since she is probably pissed too (spoiler: she is). so yeah, thats the story how my brother broke contact with my mom and I
