Does divorce occur through obsessive thoughts and suspicions, and what is the ruling on uttering the word "divorce" in my question?

The most effective remedy for obsessive thoughts is to disregard them. Divorce does not occur merely by internal monologue; rather, it requires an explicit verbalization or an implicit statement accompanied by the intention to effect it. Based on this, divorce does not occur by what you thought to yourself, nor by doubting the issuance of its necessitating cause. And you are not bound by anything in your statement: "You are divorced."
