Exbestfriend
The one person that you would die for, even cry for. But something happened. It could have been you or them. You try to break them off but that doesn’t work. You feel the guilt of breaking it off. It hurts and it will always hurt.

Human 1: I think I have an exbestfriend.

Human 2: HOLY HELL!
