You are not helpless. You are in control of your own life. Your H has made choices that hugely impact you and the kids without consulting with you, now it is your turn to do that for you. This will suck for a while... it just will. But, you will get through it. Be strong, try not to react to what he does, take care of yourself and the kids, be as fabulous as you can be! That will be good for you, no matter the outcome of your M. Breathe, eat, sleep.... you will be ok.
