Personality Disorders: The Controllers, Abusers, Manipulators and Users in Relationships
Summary
As we go through life, we encounter a variety of individuals. We also develop a variety of relationships with others including family members, neighbors, fellow workers, friends, and familiar faces. Healthy relationships seem to be healthy in the same way – having characteristics of respect, concern for others, affection, cooperation, honesty, mutual goals, etc. A relationship with a Personality Disorder is totally different. That 9 or 10 percent of adults with a “Cluster B” Personality Disorder can create significant difficulties in our life. In brief contacts they are often troublesome - the uncle who is a con artist or the sister-in-law that nobody can tolerate at holiday dinners. When we bring them into our lives however, a Personality Disorder rapidly takes over and our life becomes centered on their needs, demands, and goals. To achieve their self-centered objectives, the Personality Disorder becomes the controller, abuser, manipulator and user in relationships. The early identification of individuals who create unhealthy relationships can save us from years of heartache as well as damage to our personality, self-esteem, finances, and lifestyle.
