He may not be able to face you because of the guilt he feels. That's why email or texts are safe. He doesn't have to look at you while communicating in this way.
If you feel he's doing it as a way to 'punish' you, take that power right out of his hands. Whenever you see him you have your best PMA on. You should always display this regardless. Do not let him see you breakdown. Save that for the privacy of your own place.
This is tough stuff. Keep working at it until it becomes natural to you. I know this can be done because I do it all the time. My H sounds much like yours...
