Does divorce take effect through allusive divorce phrases or delegated divorce with the presence of intention, even if the divorcer is unaware of the rulings concerning these allusions or delegation? And is the statement "everyone goes their separate way" considered an allusive divorce phrase if uttered with the intention of divorce, and how can the wife be taken back thereafter?

Your statement to your wife, "Everyone goes their own way," is among the divorce pronouncements that effect a divorce with the intention [of divorce]. If you intended divorce at that time, then your divorce is valid. And since the wife has not been consummated with, she has become irrevocably separated from you, and she has no waiting period ('iddah). Her return [to you] is not permissible; rather, you must keep away from her. She is a stranger to you until a new marriage contract is renewed with its pillars: the presence of the woman's guardian or his agent, two just witnesses, and a dowry. If you doubted the intention of divorce without certainty or a strong presumption, then nothing is binding upon you, because the original state is the continuity of the marriage until that which invalidates it is confirmed.
