I think one of the reasons that your h continues to re-read your emails is because they are too long. Mlcers can't focus on more than several sentences at a time. When the messages are long, they have to go back many times and re-read them in order to fully understand what you or any one else has sent. There are even times, that they just skip around in the message and focus on certain words and then there are other times that they will read one or two lines and not go any further.
Keep the focus on you and your family and allow God to do his work. You have to have faith in the system and allow the time and space to do the work. It does work if you step back and allow him to focus on himself.
Take care of yourself. Don't be so hard on yourself. You didn't break him, therefore you can fix and/or cure him. He has to do that all by himself.
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.
