If it makes you feel better, he hasn't completely moved on. He uses alcohol to mask his problems and past, and his narcissistic behavior to absolve him from any fault. He's carrying around a lifetime worth of baggage that will never allow him to be a fully-functioning person in society, until he confronts his problems and puts real effort into reinventing himself.
It's hard to see things that way, because inside that resides someone we really cared about and someone who cared about us. However, we always have to remember that an addict never moves on until he or she gets help.
