Did you go through all 13 pages? Just mentioning it, because I've missed the extra pages on an article before. There is some more info. at the link below:https://bpdfamily.com/message_board/index.php?topic=70004.0
Growing up, my Dad used to practice the "silent treatment". One problem is that children can think that this is normal behavior and later subject their SO to it.
I don't think there is a standard approach to get your husband to stop. I read recently where someone just went on talking to their spouse, went about their business, asked the spouse to join them in going somewhere, etc. They went on with business as usual until the SO/spouse stopped the behavior.
