Navigating the Ethics of Cheating: Is "His Body, His Choice" a Valid Excuse?

A woman seeks advice on Reddit after discovering her boyfriend cheated on her with her childhood best friend. When confronted, he justified his actions by claiming that he can choose who has access to his body. The woman is confused and hurt by his reasoning, as their relationship was based on faithfulness. The excuse co-opts the "my body, my choice" argument used in the pro-choice movement, but it is not comparable to the right to an abortion. Reddit users advised the woman to leave him and prioritize her own well-being.
