You don’t want to invite a wolf to dinner! You don’t have to spend your precious time and energy trying to convince him he is a wolf so he will change! A wolf doesn’t change into anything else. It is always just a wolf.
When dealing with those who are incapable of caring for other human beings, you need to begin looking at it like you would the wolf. He is what he is and you can’t change that! So you may as well set him free to his own experience in life and free yourself from his energetic control.
