Is AUTHOR wrong in the post ? POST : So I was friends with a girl who I really loved and she got into a relationship with a guy, and I didn’t feel good about him. He seemed sketchy. I wanted her to be happy so I didn’t say anything. He ended up almost doing some really bad stuff to her and I cut her out of my life because I felt guilty for not saying anything. AITA?

(This is something a friends asked me, not something that happened to me)
