“It’s Not Me, It’s You” is a phrase often used in breakups to indicate that the person ending the relationship believes the other party is at fault. This expression suggests that the issues in the relationship stem from the other person's behavior or characteristics, rather than any shortcomings of the person initiating the breakup. The phrase has gained popularity in popular culture, appearing in various forms of media, including movies and books. It reflects a common sentiment in relationships, where individuals seek to distance themselves from blame while addressing the challenges they faced together.
