So LotsaKnots, take a deep breath and think this through.
Stop thinking he has all the control. Get that idea right out of your head. He only has control if you give it to him. So take control here.
Stop thinking about what he wants. Right now, stuff what he wants.
What do you want? Focus on that.
You probably want for this to never have happened, sadly it has. So, how do you feel, about him? Can you carry on with a man who has caused all this pain and confusion? Can you forgive the nasty things he said? Can you forgive what he told the kids?
I think you have been to hell and back in the last few days. But I also think you have surprised yourself at the way you've coped, how you've tackled the practical stuff. Regardless of crying to strangers on the phone (we've all don that) you did it, you fought through the tears, you did it, good on you. You're stronger than you think.
So don't be passive and wait for him to decide your future. Grab control of your future, your kids future. It might be with him, it might not. But you decide, not him.
You are justified, because of what he's done, to tell him that you need some space to process the events of the last few days, and suggest he leaves for a few days whilst you think it all through. This gives you the space to get your head together, and him the wake up call he needs, making him realise that he's dealing with a strong, independent woman, not a little girl he can mess around with.
I wish you well.
