You have to come to accept that he is an adult making adult choices to kill himself slowly and thats the sad reality. Addiction is awful.
You have to get to a point where you choose yourself and your boys and nothing else matters.
I know it hurts. I worry about separated AH every day but he is choosing to live this way and has to deal with consequences. Meanwhile, I have to be away from him so I can be the best version of myself for myself and my children.
