If this cruel mother ended her marriage to LW's father, would that be a bad thing for LW's father?
Some of the reasons it might be bad:
He might be sincerely attached to her.
There might be financial reasons (splitting assets is difficult even in an amicable breakup), and not everybody is always equipped to start a new life on their own, particularly after many years together. There might have been a prenup that would make things more difficult for one of the people involved.
They might both depend on the income or health care attached to one party.
Splitting up might change what any children would stand to inherit.
