This happened a few years ago(2019), but my sister (now 31) still brings it up and thinks I’m still in the wrong… I really don’t think so.

My sister we will call her Stacy got married in 2019, with her now husband for 10 years at the time of the wedding. She’s always been very popular with a larger wedding party they decided to rent a really nice house in the mountains/ mostly couples with one stag groomsman. I am her only sister (now 30) not the maid of honor and the only person in the wedding party with a child (now 9) my son and I were more then happy to get a hotel room as I figured they would be up late and a baby would cramp their style. Well my sister insisted we stay at the house/ and my mom was to pay my part for the house. My partner was originally not coming to the wedding due to shoulder surgery so we agreed as I thought we could get our own room and go to bed early. We’ll about a month prior to wedding surgery was moved up and my parented was able to go to the wedding which i communicated to my sister/ asking again if we should get different accommodations. She said no, and I heard nothing more about it. We came a day later than everyone else in the wedding party and realized we were left with room that was not going to work. She had us inside a closet with twin beds inside another couples room.. clearly the air BNB renovated the closet to be for small children. I argued with my sister as I had myself, partner and child with me. I threw a fit if were being honest and called my mother and threatened to leave and go home, my father got us a hotel and I did not apologize to my sister as I did not think I was in the wrong. The wedding went fine, I didn’t stay for the whole reception but overall I heard nothing else about it. Well apparently my mom never paid my part for the house because I didn’t stay there (I didn’t know about this) so my sister has been holding this grudge against me ever since then for being a brat and getting what I always want? Maybe I’m missing something here but I really don’t think I’m the asshole, Thank you
