Breathe! No, there is nothing you can do to stop the divorce if she files. You may attempt to slow it down, but it will cost you a lot of money to do so and will anger her even more so.
Breathe! Have you spoken to a lawyer to see what your options are? If not, you may want to consult w/one just so you know what to expect...but otherwise, there's nothing more you can do in the way of stopping a divorce if she files. I'm sorry that she's on a roll...but now you need to really, really focus on you, your health and your children.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
