Let’s start with some casual, everyday ways to gently tell someone, “It’s not me, it’s you.”
Part 1: Casual Suggestions
1. あなたのせいだよ (Anata no sei da yo) – “It’s your fault.”

This is a straightforward way to say “It’s your fault” in a casual setting.
“あなた (Anata)” means “you,” “の (no)” is a possessive particle, and “せい (sei)” means “fault” or “blame.” Adding “だよ (da yo)” makes it more informal and conversational.
Great for when you want to be direct but keep the tone light with “よ (yo).”
Just be mindful—it can sound a bit blunt, so use with close friends or in less formal situations.
You might hear a softer alternative like “ちょっとあなたのせいかも (Chotto anata no sei kamo)” meaning “It might be a little your fault.”
Remember, tone of voice matters a lot in Japanese; soften your words to avoid sounding too harsh.
2. 私じゃない、あなたよ (Watashi janai, anata yo) – “It’s not me, it’s you.”

This phrase literally means “It’s not me, it’s you,” and is the closest direct translation.
“私 (Watashi)” means “I” or “me,” “じゃない (janai)” negates it to “not,” and “あなた (anata)” means “you.”
Adding “よ (yo)” at the end emphasizes the statement in a friendly way.
It’s clear, simple, and effective for casual breakups or honest conversations.
Be careful not to sound accusatory; soften it with your tone or follow up with a gentle explanation.
