I have a son-in-law that is very OCD (controlling, demanding and harsh). With the scary economy he has become even worse and my daughter filed for a divorce. The problem is my granddaughter. If she chooses to go over to his house there is always a huge battle over the slightest of things. Any idea? … He refuses to take medication or get help. Even at the cost of his marriage and my granddaughter’s happiness. ANY IDEAS?
