Is there a fraud claim/complaint, bar complaint or any violation of law because we did not take out our recent taxes when chapter 13 dismissed?

My spouse and I filed a Chapter 13 and it was granted. My wife soon after six months convinced me to sign a separation agreement so that we could file a chapter 7 separately after having the chapter 13 dismissed. We, or I, I guess, had no intentions of separating none the less divorcing. She now wants a divorce and is holding the separation agreement as a basis that we are not living together and she is solely responsible for the mortgage to make sure she meets the means test for the chapter 7. We are about file for chapter 7 with the separation agreement in hand. Is this fraud? She says "no" because now she wants to get a divorce although that was not the pretense of the separation agreement. It was to deceive the Court. We also owe back taxes, which were not taken out of our recent tax return when the chapter 13 was dismissed. I am at huge disadvantage because she is an attorney that handles divorces and bankruptcy cases. Am I just screwed because I signed the separation agreement Will I or both of us go to jail?
