A comprehensive understanding of domestic violence/intimate partner violence and narcissistic abuse can be found here: Knowledge is Power.
"Defined by emotional volatility, a lack of empathy, and delusions of superiority and entitlement, Narcissistic Personality Disorder is linked with interpersonal exploitation, rage, and aggression, most often directed at family members. Making matters worse, narcissists compulsively deny their behavior and project it onto the people they hurt, and they frequently cultivate a likable or even do-gooder public persona that belies their ongoing abuses behind closed doors."
"MYTH: Adults can just leave the situation. Leaving an abuser, especially a highly manipulative and vengeful narcissist, is rarely easy to do. Partners of narcissists, particularly women, are frequently isolated from friends and family, drained of financial resources, and bullied into compliance with threats of assault, withdrawal of support, loss of child custody, and homelessness. Often they are victims of childhood trauma, with vulnerability to abuse cycles."
