The chains that keep you bound to the past are not the actions of another person. They are your own anger, stubbornness, lack of compassion, jealousy and blaming others for your choices. It is not other people that keep you trapped; it is the entitled role of victim that you enjoy wearing. There is a familiarness to pain that you enjoy because you get a payoff from it. When you figure out what that payoff is then you will finally be on the road to freedom.
