So sorry that you are going through this-This disease is a horrible thing-
Pray and stay positive that God will give him another chance-if that is what you believe in your heart.
IMHO I do not think we can ever prepare ourselves for such a horrible thing like this to happen-however I do believe that whatever the outcome it is truly the right thing at the time.
If we believe in our HP that we will be carried through the rough times. I too went through this with my father (drinker) and it was then I had to put my hope and faith in my HP. I had a lot of regrets with my Dad and I was able to work through them today....never let go of the hope-
Try to let go of the past and the anger you feel for whatever else is going on and just pray for him-
Sending prayers your way
Hang in there-
