His visitation rights to his son are clear and outlined in their divorce papers, he has him (and also B) 4 evenings per week, overnights every Friday and Saturday nights, and all day Sundays. (She loves her “me” time.) He doesn’t have to take B, he has no legal right to. He feels it’s his responsibility to have him also, even though having him sabotages any relationship with J.

I think this is more of a moral issue than a legal one. Is he morally obligated to continue taking B, knowing it’s going to be unpleasant and chaotic and detrimental to his son?
