It is helpful to hear from other adult children who come from a childhood of emotional trauma and what they felt when their second parent did in fact chose to limit or change the amount of contact. He NEEDS to hear what could happen to his relationship with his son and Grandson if he does decide to change how things look right now.
If, at the end of the day, he decides that he does not want to see his son and grandson without his wife, he did so understanding how the relationships of others in similar situations turned out.
I really will never understand some of the things said on various threads here on GN.

Which is it?
