My ex accused me of fraud in ch 7 and US trustee filed adversary action. But they realize they have been duped and pulling back. What is my recourse?

My ex just wanted me to get into trouble so ex accused me of hiding assets from ch.7 bankruptcy trustee by providing information ex gained in separate family case hearing from me. Even though ex knew the money I received after bankruptcy case was legitimate gain after ch 7 filing therefore mine, ex lied to trustee it was from litigation settlement so trustee will come after me. They were facing deadline and had to file file adversary action against me without time to investigate because my ex made claim so close to deadline. Long story short, trustee does not think they have claim and case is going to close. In the reporting website DOJ even has the warning to deter some one like my ex. “No, you cannot be assured that your identity will be protected, but you can report fraud anonymously. Furthermore, you are not immune from suit either. If the debtor or the accused person is later acquitted in a criminal proceeding, you may be sued for malicious prosecution”
