Silent Treatment

In my experience, fighting can be productive thing as it airs out problems before they get out of hand. But only up to a point!

The best thing to do after a fight is simply go to a neutral corner: get out of each other's faces and allow some time for tempers to cool and reason to step back in. He'll start talking again after awhile.

Let cooler heads prevail. The silent treatment means he's still upset about things, so talk and let things out. That's the only way you can patch things up.
