Hope, As your H yells at you for stupid things.....if they are really stupid, then you continue to do what ever it is you were doing. And eventually he'll get the point, get over or die with it on his mind. You as a mother know you can't give into your child when he's whining and being ornery just to be whiny and ornery, it goes for adults too.
Remember this: You are going to survive this and one day your H will regret how he did this and how he treated you. When that day comes, you won't care.
On the little things, this does work. H eventually calms down when it gets little reaction from me. But there's an intensity and rage to his voice that sends shivers down my spine.
