I’ll try to keep it short. So I (26f) had been friends with a pair of sisters for YEARS. We would argue here and there, but it rarely escalated, and we were always there for each other. In the past few years we didn’t talk as much, but I still considered them some of my closest friends. WELL, recently I learned that one of them has been talking about my sister’s sex life to our niece (niece is 13 at the time, and friend is about 22f). I found this absolutely disgusting, and after my sister told me about it, I left the group chats we were in together and blocked my “friend” without a word. Now friends entire family has me blocked as well, and friends sister sent a paragraph to my sister saying how we “ruined their lives” and stuff like that. I guess I just want to know if I took it too far by blocking her? I’ll answer any questions if this was a bit confusing
