Emotional blackmail

Negative form of psychological control over another

Emotional blackmail and FOG are terms popularized by psychotherapist Susan Forward about controlling people in relationships and the theory that fear, obligation and guilt (FOG) are the transactional dynamics at play between the controller and the person being controlled. Understanding these dynamics is useful to anyone trying to extricate themself from the controlling behavior of another person and deal with their own compulsions to do things that are uncomfortable, undesirable, burdensome, or self-sacrificing for others.
