I'm in agreement with the others. He's expecting your son to be distraught and lash out at you for "breaking up the family" (though I'm almost certain your son knows exactly who daddy dearest really is). If I had been older than 4 when my parents split, I would have helped my AM pack and shoved her out the door. I do see a rager coming when your AH doesn't get what he wants, though. Be prepared for a real ******** in front of your son. If it doesn't happen, then just be grateful for the miracle. (((Hugs)))
