Hi J48 I’m so sorry for you and your son over your loss. I really hope that in time you can both look to a happier future. From the things you’ve said your husband loved you both very much. I agree that there is some kind of darkness in addicts that needs to be addressed for them to get better. For that they need professional help. Men can be so proud and stubborn and seem to find it hard to reach out and open up. You sound amazing and would have been a huge comfort to him.
God bless you both.
