AITA for unfollowing a girl without removing her?
I had vaguely interacted with this girl in HS to let her know some guy was saying they were dating when they obviously weren't. After a while she unfollowed me and removed me on Instagram and I just unfollowed her. Fast forward to University and we go to the same university. I saw another post saying awful things about her and I decided to let her know. (I generally tell people if I hear someone telling groups of people awful/false things) She said thank you and we had a couple of other interactions. Anyways, I heard her talking bad abt someone and I decided to unfollow her. I went to class afterwards but by the time I left class she had sent me a paragraph about how she's never going to be nice to someone like me and that she's not a fan. I told her I didnt realize how much of a b**** she was. Tbh it was all I could think. We argued and then i blocked her. Her friends started messaging me and saying similar stuff so I blocked them too. She emailed me through my school email threatening to sue me for defamation? Even though she's the one who had people message me? Is unfollowing without removing someone really this serious? AITA for unfollowing without removing?
