I think that if you want to drive your wife away, then by all means, give her that speech.
If she wants to file, you cannot stop her. You can either confirm her decision as the right one, or you can make her wonder if she is doing the right thing. I say do not go through all that crap with her.
Dude, I get that you are angry and hurt. We all are. You need to move past all of this pain and fear. Women sense fear, and you are wearing it on your forehead. Fear not the future without her. When she sees this, you will be a more attractive alternative.
