Addiction is hell, damaging and all consuming. When I drank I was selfish- YES. I have no logical or rational explanation for addictive behaviour. It destroys- utterly. I empathise with you. The only out- is through very hard work and proactivec hoice. HIS battle- not yours. To move on- you- for yourself have to navigate through the anger. What good does it do you? Will it change him?
