WR, Breathe! Your h is trying to play the martyr to your son. He wants to blame you for everything, which in fact, he's the one that started the entire mess. He wants your son to believe that he has no money because of the divorce proceedings. He is trying to gain your son's trust and win him over to his way of thinking. I also think he did this deliberately so that your son will tell you so that you will push harder on the paperwork.
WR, I know you aren't going to like what I have to say, but I'm going to say this because you are doing exactly what he wants...let the system do its job. Don't push harder. Let this man sit in his pot of juices. He is knows that you will jump through hoops when you are angry. Settle down, relax, sit in a comfy chair and kick your feet up. Time to make him sweat some for a change.
Yep, the holidays are here...it brings the crazy making out in the pod people. They aren't happy, therefore no one is going to be happy either. Take the high road and do not let him see you sweat! Don't fall for his games of passive-aggressive behavior.
It's going to be okay. Let him spin his tales of woe. Your son should know better and what the truth is.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
