"It's not you, it's me"

The phrase "It's not you, it's me" is a common way to explain that a breakup or decision is personally about the speaker rather than the other person. It suggests the speaker feels their own qualities, feelings, or circumstances are the reason for the change, rather than any fault or issue with the other person. This approach aims to soften the message, avoiding blame and focusing on the speaker’s own reasons, such as personal growth, emotional readiness, or differing life goals. Ultimately, it's a way to communicate difficult news while minimizing hurt.
