I think you need to discuss this with his parents... I would not send it behind their back or they may turn on you... your call there, but I think you being honest with them
SOrry Mom and Dad, our guy has put me in an awful position here and I dont' have much alternative other than to report what he's donig to his superiors at work. He won't cooperate and I have a family to protect. I am aiming to end the affair and expose OW who is the source of the problem. I want you to know I don't want our guy hit in the crossfire, but I can't promise you exactly what will happen. I am trying for minimal casualties on his end, honest I am...
So at least they have a heads up... but make sure they don't reveal this to him or he will act on you first.. you dont want your H to get any warning... his parents if they are in your support group should be kept in the loop... but if you think they may warn him...
