So I'm pondering all this, Rodrigo. I think I've been on both sides of this equation although I'm not sure I'd call it ghosting. It felt more like the friendships didn't really work for one or the other anymore--like we'd grown in different directions. I'm not sure I would call either one of us narcissists. Is it a lack of empathy to not want to hurt someone's feelings? I suppose in my case though, it was more of a fading than an abrupt end, so maybe I'm not talking about the same thing.
