Is what the questioner is doing to overcome the whispers of divorce correct, is he on the right path to getting rid of them, and what is your advice?

The cure for obsessive-compulsive disorder (waswas) is to ignore it and not preoccupy oneself with it. What you are doing by researching and acting contrary to the waswas is not ignoring it, but rather engaging with it. As for what you mentioned about acting contrary to the waswas, the meaning is not clear to us, and therefore the matter needs clarification from you. We emphasize fearing Allah, seeking refuge in Him, and seeking His protection from Satan, while consistently reciting the Mu'awwidhat (Surahs Al-Falaq and An-Nas) and reading Ibn Qudamah's treatise "Dhamm al-Musawwisin" (Censuring the Obsessed).
