Why use the term dominance behavior versus abuse, bullying or narcissism?

Dominance behavior is a blanket term that covers all behaviors aimed at getting the one-up position in a relationship.  While something as basic as a sigh or eye roll can be more subtle disrespectful attempts at getting the top position, these behaviors do not fit the severity of abuse or bullying. Often times people accuse another in a relationship as being a “narcissist” when a certain air of superiority is present.  The accusation implies that someone has narcissistic personality disorder which is a very difficult disorder to treat.  Many professionals advise others to leave relationships with people of this diagnosis because it is so difficult to treat.  Dominance behavior is more fluid where people can be more controlling during times of anxiety and much more collaborative when they are relaxed.  Definitive labels such as “narcissist” limit our options and our power in relationships.
