(((((Hope)))))
I'm sorry - I know how devastating this can feel...it truly stinks. I know you know you can't do it for him, but that doesn't make it any less difficult when this happens.
So many recovering addicts I know tell me that each day clean makes a difference and is a step towards recovery. Maybe there is something he hasn't quite figured out...maybe he had a reservation, and so this relapse will be one that brings him closer to embracing recovery.
I found I needed face to face support even more when my duaghter would relapse. Picking up a few extra naranon meetings helped me through rough times...and so did SR. Hugs and prayers for both of you.
