I know how hard it is to face those feelings of powerlessness. Watching a train headed at 100 miles an hour for your family and you are powerless to stop it.
The wreck itself, however, is the thing you are powerless over. Your H is driving the train right now. Leave him to it.
You can, though, shield your kids and your heart as much as possible from the debris and the impact when it hits the fan. That's where your power comes into play. Build a fort around your heart right now, be gentle with yourself, don't trust him a bit and, please, please, please, create a nice soft spot for your kids to land. They will need you more than you ever thought possible.
Focusing on his poor train driving skills aren't helping them right now at all. It's only robbing them of BOTH parents.
