I have to agree drained...there's no longer a need for an explaination, or proof, or any of the "plans" he continues to make.
As far as counsleing, it sounds to me like its just another avoidance tactic to side step the drug issues. Trust me, your husband admits to enough substances to be a drug addict. It doesn't matter where they came from.
And the dance continues...
