agree with sparklekitty.
so I think it is imperative he understands the disease
why?
i dont see how understanding alcoholism will help keep things civil during communication.
you can keep things civil,though, by not allowing yourself to be a doormat or allowing unacceptable behavior. you are allowed to stand up for yourself,now, babes.
i would say it would probably be good for the family. but not so much about learning about the disease, but learning about himself
