In his early 20's my husband was diagnosed as a narcissist and I was advised by our marriage counselor not to marry him. I didn't at the time but several years later he convinced me he had changed and we married. I have known him for 40 years and we have been married for 28 years.

Throughout the marriage he became physically, verbally and emotionally abusive. Two years ago he tried to be physically abusive to our 20 year old daughter. Police have been involved. He has been to a year of domestic abuse and anger management counseling, but it has failed and he remains abusive. His last act of abusive was his infidelities with 5 women over an 18 month period.

We are just starting an online EMS program, but I fear the heart of our problem is the narcissism.

Can a narcissist change and should I continue to invest in this relationship or can I now please just leave?
