 Your husband and his dad can choose to have a relationship in spite of the Parent PLUS loan issue and without you agreeing to pay the Parent PLUS loan. And so at no time have you destroyed your finances, have you traded the destruction of your finances for the relationship. If your father-in-law is so manipulative he wants to make that trade that the only way you have a relationship with me is you pay this loan, then he has chosen to destroy the relationship. But you and your husband didn't choose that.
