I'm wondering now if this is just another game with him to get a reaction out of me as far as not giving our D13 the exact address.
No I don't think it is a game, he is just still in his fog and nothing but the fog is on his radar. I would just let it go and keep living your life without him. I would tell the school the truth. You don't know his address. It is not YOUR problem. It is the schools problem. Let them get in touch with him.
