Treatment and therapy for manipulative behavior may depend largely on what underlying issues are causing the behavior. If, for instance, the manipulation is being caused by an underlying mental health issue, individual therapy may help that person understand why their behavior is unhealthy for themselves and those around them. A counselor may also be able to help the manipulative person learn skills for interacting with others while respecting their boundaries and address underlying insecurities that may be contributing to the behavior.
Certain mental health issues such as borderline personality may cause people to feel anxiety in relationships, causing them to act manipulatively in order to feel secure. In these instances, a therapist may help the person address their mental health issue, which in turn can reduce their anxiety and help them feel secure in their relationships.
