"......This is not what I wanted for him."
Trust us when we say, it is not what he wanted for himself either, just try to find some small comfort knowing that he is finally free from his demons.
A very wise lady once posted this here at SR:
"Love cannot save our addicted loved ones, if it could, not one of us would be here." Truer words were never written.
Keep coming back,
