A person who actually cares about you will tell you when you piss them off.

This is so true! Many of my friendships have had to pass this test, and I appreciate those people because of it.

My most toxic "friendships" was with a woman from work with a victim complex the size of Texas. She pretty much would make every interaction about her and how everyone was out to get her. I was not invested enough to explain that most people probably just couldn't stand her deeply negative and self-centered approach to all human interaction. In the end she moved away and I breathed a sigh of relief.

I still follow her on facebook for the entertainment value though.

edit: ALSO, your post brings up interesting points about online-origin or online-only relationships, in that ghosting is much easier. If you saw someone regularly face to face, I think you'd be more likely to have a real argument at some point, after which you might reach some emotional conclusion that offers closure, whether that's "let's work through this" or "never speak to me again".
