Mrs. H, I suspected all along that he was pumping the children for information. It's any wonder your son is down lately. Your h is using him for information and putting him in a very difficult spot. Shame on him for doing this to your son! It's too bad you weren't recording this particular conversation.
Are you sure he didn't hear you pick up the phone? He may have been telling S7 this crap just to see if you would speak up. He's really a paranoid man and will try anything to get you to take the bait. Do you have any errand running to do tomorrow night? What about Tuesday night? I think it's time that you and the boys go to the park for a little bit and enjoy the beauty of God's work and get some much needed fresh air.
If JA should show up, do not let on to him that you knew about the conversation w/your son. I think it's time your JA realize that you aren't the civic center for meeting up and realize that his visitation schedule is what he needs to adhere to. I can't help but wonder where the Ho is in all of this.
No 2 X 4's on you, but I sure would like to use one on him.
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.
