Listen, father provided a good life for the kids and the wife when the business was running well, so he is a bit childish and stupid, so he has fallen from grace and doesn't know how to properly handle kids, he still gave them everything, he even regrets the outbursts and he himself deep down loves wife and the kids enough to himself suggest to divorce and go to prison to take accountability for his actions. Real wife needs to step up now that she is the breadwinner, gave the vows, for better or for worse, if he is dumb, she needs to whip him back in line, her turn to make a good life for everyone in the family, to make him see light, he is good guy deep down, he only wants what is best for the kids, he just doesn't know what that is. Bonus points if he was also a loyal husband and never cheated on the wife.
