My husband (36M) and I (36F) have been together for 11 years married for 9. We don't have any kids because of my husbands cancer (I don't know if that is relevant but I feel people will ask). My husband and I have one of the greatest marriages I have ever seen, we always make each other laugh, feel loved, cared for and there isn't a day where if I thought about him I didn't smile.
We have this little game where we joke about him being abusive, in an extremely cartoonish way. It began when we started dating and his 4 sisters, his mother AND his grandmother all assured me he was a very kind, gentle guy. Not the type to be abusive AT ALL. Since then, we always made a joke about it.
When my husband and I got married, his best friend (36M) and my sister (33F) ended up meeting and kinda falling for each other. It was sweet but they didn't do anything about it for 7 years, At a family BBQ they just couldn't resist each other and ended up sneaking away. They got married 6 months later and then to everyone's surprise divorced a year after that. We are the only ones who know the real reason why the divorce happened and my husband ended up losing his best friend. My husband has hated my sister ever since.
That's the backstory.
This Christmas we were opening gift with my family and my husband jokes "I swear to god OP, if this gift isn't the PS5 I asked for, I am taking everything back and you are OUT!" (He doesn't even play video games and it definitely wasn't a PS5.) Since then though some of my extended family has been acting wary of my husband and have been asking if I am okay, and if I need help, I just have to ask.
Two weeks ago I found out why, my sister has been going around and telling everyone my husband is ACTUALLY abusive and she KNOWS what an abuse victim look like because her ex husband was abusive and that is why she had to leave him.
I decided to do some damage control and tell everyone the truth. She didn't leave her husband because he was abusive. HE LEFT HER because she cheated on him with 192 guys in a single year. He was working massive amounts of overtime so he could buy her dream home, meanwhile she was on Tinder hooking up with sometimes 2 to 3 guys a night. She blamed it on being a sex addict and he was working so much and they weren't have sex as frequently so she went out and found it somewhere else.
My sister blew up at me, screaming at me, saying her private life is none of anyone's business and how dare I tell people about her addiction. My mom thinks I should have handled it a different way and shouldn't have humiliated my sister that way. I feel I am justified, but maybe I did take it a little too far.
AITA for telling everyone that the real reason for my sisters divorce is because she cheated on her husband with 192 different guys in a year?
