Do nothing until you talk to an attny. Do not share anything with her you learn at the attny. It is not your job to inform her of the legal proceedings and the avenue you will pursue for settlement. If she has questions tell her to have her attny call your attny. Do not waive your rights to legal counsel, do not agree to "file together" or anything else. If she wants a divorce, no problem, but make sure she knows you will be playing ball and not blindly following her two bit schemes to make it all lovely and fair.
There are many threads on the forum about talking to children.
