"Saying I do" is a term that is mostly associated with getting married, where both parties pledge their love, commitment, and willingness to spend the rest of their lives together. However, there are several antonyms that describe the opposite of this term. A person could say "I don't," indicating reluctance, unwillingness, or a lack of desire to get married. Alternatively, someone could say "I'm not ready yet," symbolizing that they are not yet prepared to make such a lifetime commitment. Moreover, "I refuse" could be another antonym that describes a person declining to enter into a marriage agreement. Thus, while "Saying I do" represents love and devotion, its antonyms suggest the opposite: doubt, hesitancy, and refusal.
