to be blunt, his mission has been to either get high or get laid.......one is addict behavior, one is simply inexcusably indiscriminate behavior.
not to hi-jack here, but it is my understanding that both of these behaviors are addict behaviors -- in that they are compulsive behaviors whose roots lie in unresolved issues with the self.
if drug addiction is not labeled an "inexcusable behavior" we cannot label compulsive infidelity & sexual behaviors as such either.
