CVA, As you know, I am still married, for the time being, anyway, to probably the queen of denial, so I know exactly how you feel.
I know that it is hard, but you need to push it away, let her act like that, in time, and I speak from experience on this, the blinders will start to fade, because, deep down she has to be feeling the guilt about all of this, any sane human being would be, it is a matter of I can't let my husband see just how screwed up I am, cause then he wins.
It seems like to me that a WAS's only concern is being the one on top, and controlling the sitch. Don't let her! Even though she filed, you still have the power, and you decide how you are going to react, whether it be in a legal sense or not. Let her know that you will fight for your happiness, and rights to be a father to your kids. I have faith that you will let her know that, one way or the other, that she is in for a fight and once that reality hits her like a cold slap in the face, she will have to deal with everything, she still she might not want to show it. but know that it is/will take place. Take care.
