How can one turn away from the obsessive whisperings of divorce for an obsessive person who loves his wife and does not want to separate from her, especially since the intention of divorce pushes him with every utterance, and given that Ibn Uthaymeen's fatwa states that the divorce of an obsessive person takes effect if he intends by it to get rid of the obsession? And what about continuing to take Prozac?

Your turning away from obsessive thoughts is one of the greatest means of treatment. Turning away means resisting the obsession, not giving in to it, and not considering a divorce that is caused by an obsession. Sheikh Ibn Uthaymeen, may Allah have mercy on him, denounced those who proceed with divorce to get rid of obsessive thoughts, considering it a grave error desired by Satan. As for Prozac pills, you should consult the specialist doctors in the مشاكل وحلول (Problems and Solutions) section of the website.
