You are still operating under what is called the "illusion of action" and that you have to do something to get a reaction out of her.
She doesn't care who she hurts that is so obvious.
If you need to do something. DO NOTHING, which is something. Start planning a life for you and the kids and start to formulate in your mind what that life might look like.
Again, you are still waiting for the big decision which has already been determined by her months if not years ago.
Like Neff said, put on your big boys pants move forward in your life, take care of your kids and the rest will take care of itself. Let her file, let her do the heavy lifting.
