GM, I am sorry that he's acting like a complete and utter @ss. If the messages are about what will be discussed in the meeting, advise him to hold his questions until then. You don't have to get into any long winded conversations about those things, as they will be discussed later.
Take back control over your life and if you think his emails are not worth responding to, delete them. Nothing says you are at his beck and call 24/7. The only messages you might want to respond to are those directly related to the boys.
The delete key is only a button away. Don't allow him to wear you down for that is what he is attempting to do. He wants to make you a basket case so that you will agree to anything to get rid of him.
Please take care of yourself.
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.
