I did leave him but I waited too many years. He did go to marriage counseling but refused to go back once our psychologist marriage counselor told him he lacked empathy. He did not believe he had a narcissistic personality disorder. Of course, that is the norm for a narcissist. I’ve spent a decade in counseling and research of narcissistic personality disorder. Unfortunately, even when our counselor explained to me it would be rare to impossible for a narcissist to be reformed I wouldn’t give up and wanted to believe in miracles. If you are with a true narcissist one with the accompanying traits and the distinguishing lack of empathy they will not benefit or most even attend counseling. This is because of the disorder itself. The lack of empathy prevents the narcissist from self-reflection because they have zero ability to look outside their world and into the world of others. For this reason, most narcissists (the majority go undiagnosed for this reason) who are diagnosed are done so under secondary means. It’s detected if they seek treatment for something else, i.e. addiction or other medical issues or if they actually do go to marriage/couples counseling.
