Deception is not a part of recovery. If he's cutting corners and lying he on shaky ground and is planning to relapse or setting himself up to.
You can't manage or control his recovery anymore then you could his addiction. Both belong to him.
We can get so caught up trying to make sure they do right thing... but the hardcore reality is you can't make him get clean or remain clean and trying to will only make you sick.
Detach, find your own recovery and work it. That way you will be okay no matter what he does or doesn't do.
