The silent treatment is another control tactic, in an attempt to draw you out. To make you beg for contact, being a warm person contact will be part of who you are.
Stonewalling, silence and it is trying to punish you.
Ignore it, see it for what it is. If you accept this high level tactic and go with it then you may get peace at least for a while.
This may last for about 4 weeks if you are luckily although your WH cycles quickly, mainly because he thinks it works.
Whistle a happy tune, enjoy the space.
