Can you get him into counseling? He needs to understand that the trust has been broken, that it takes time to rebuild and that he must do most of the work to get there.
Hopefully, some wise DB'ers will chime in and give you some sound advice. My 2 cents says he's not fully accepted his role or the damage he has done. He doesn't seem remorsefull at this point.
Good luck - I am sure some DB vets will chime in. Know that you will get great advice and support on this board. I wish you the very best.
