When a man’s face contorts in bitterness and hatred, he looks a little insane. When his mood changes from elated to assaultive in the time it takes to turn around, his mental stability seems open to question. When he accuses his partner of plotting to harm him, he seems paranoid. It is no wonder that the partner of an abusive man would come to suspect that he was mentally ill.
Yet the great majority of my clients over the years have been psychologically ‘normal.’ Their minds work logically; they understand cause and effect; they don’t hallucinate. Their perceptions of most life circumstances are reasonably accurate. They get good reports at work; they do well in school or training programs; and no one other than their partners—and children—thinks that there is anything wrong with them. Their value system is unhealthy, not their psychology.
