He says he's not addicted. He still works and goes to the gymn and functions - if this is true - then wouldn't it be different than being addicted?
Hope- I'm no expert, but I have heard of "functioning alcoholics" before (I know in your H case it's drugs). I think there are MANY people out there who tell themselves they are just fine b/c they're holding down a job and no one perceives them as an addict. But they are. I don't know if your H is or not, but I do think it's possible for someone to be- even if he does all those functioning things--
PS- found ya on FB :-)
When the men on the chessboard Get up and tell you where to go; And you've just had some kind of mushroom And your mind is moving slow; Go ask Alice... I think she'll know.
