Sorry you are here, but you are surrounded by many wonderful people here.
Like Job said, let her make the decision to move to the other room or not. If you force it, that will be used to justify her behavior and feelings. It's difficult to sit back and be patient, but trust me, I learned a lot of things the hard way by reacting on anger and emotion instead of letting things play out.
It can be a long and difficult road. Right now do your best to focus on your kids and yourself. You will need to be the stable rock for them.
