AITA for RSVPing no to my brother's wedding for my family even after he begged me to let us all attend?
I (34F) have a younger brother (technically half) from my mom who is 26 and he is getting married. My brother's dad and my mom were engaged for a couple of years when my brother came along. When he was 1 my mom found out his dad was cheating. His dad packed up and moved in with the other woman and married her three years later. My brother split his time with us and with his dad equally. It was always awkward when we were around his dad and his dad's wife. She was always super hostile to my mom and super insulting to her. My mom kept her mouth shut through it all. She did not fight back. She would try to keep my brother out of the middle. But my brother knew about it all.
When my brother turned 21 he had this big birthday party and we were all there. During the party his dad's wife called my mom yesterday's news and said she wasn't the kind of woman a guy marries. My mom fired back that at least she didn't sleep with men in relationships with others. My brother heard the entire exchange but scolded mom for what she said. Mom got so upset that she quickly left. I asked my brother how he could let his dad's wife talk to mom like that but only scold mom. He said mom has always been better than that and he expects it to continue. I told him he wasn't a little boy anymore and shouldn't expect mom to always accept the hate and that...
