It';s not your job. Tell the son that he is to let his mom know where he's going. He probably can't take the insanity any more than you can! You can offer the son sanctuary until it's time for him to go home. But boy is the MOM way out of line! Until they are irrevocably divorced and custody is determined, the boy has two parents. He does anyway. But you need to be able to have contact with one of them when he's at your house in case of emergency. Dads are just as possible. She's playing a tug of war and I wouldn't play into her dramas. She's pissed off. She doesn't need to make everyone around her miserable. Next time you talk to the dad, explain this load of hooey and that you do not want to be in the middle. Your sons are friends. That should be a consideration on their parts, without demanding you take sides. Hang up on her next time.
