Does a husband's review of his wife [i.e., of her status as his wife]—as a precautionary measure and to guard against divorce occurring due to obsessive doubts—affect the marital relationship, assuming that no divorce has actually taken place?

The utterance of رجعة (revocation of divorce) by a man suffering from obsessive doubts does not constitute a divorce and does not affect the marital bond. Revoking a divorce out of fear that it might occur, or believing that it has occurred, does not make it happen. He must, therefore, ignore these obsessive thoughts.
