Yes, unfortunately you cannot legislate everything. Before the family law reform act which directed couples to split the assets accumulated during a marriage, as well  equity in the matrimonial home, divorced women often had to raise children with neither the assets nor income from the father of their children. I suppose it trapped unhappy women in painful marriages but it meant that things went south very fast at separation. Men "owned" body and soul of their mate, and without it, they felt they were not obligated legally or ethically to support anyone. At least now an intelligent man or woman can protect those assets which had not contribution from nor intended use by a wayward spouse. And children are at least "supposed" to be the responsibility of both parents. Perhaps you should consult a lawyer before you get involved again.
