Be proud of yourself you had the strength to stop enabling. All you can do is literally pray for him/love him from a distance. There is nothing you can do! It is so hard when those we love battle addiction, hence this forum.
Come on here and post when you need some support. We will be here to support you when you're feeling sad or down and stand behind you because we all have been disappointed by those we love so deeply and our families have been torn by alcoholism as well.
Treat yourself well. One day at a time.
