Oh wow. I am sorry that you have to deal with this still.
I have no idea but I know this isn't anything close to what my STBXAH was like when he was in recovery. He was humble, thoughtful and remorseful. Unfortunately, he relapsed and hasn't made back to the rooms (yet). When using/drinking, he becomes so manipulative, dishonest and often times has an angry tone. If he tries the blaming routine, I hang up. I refuse to listen to that crap ever again.
Addicts are great at cheating drugs tests. Are you sure he is clean?
