I wish you the best and hope this problem doesn't last long.
I wonder if the guy just felt too guilty about what he was doing and so you became his 'scapegoat'. There's my unprofessional analysis anyway.
You deserve a pat on the back for what you are doing and how you go about it. We need more people out there who love their work.
