直接d既:

I want to break up.我要分手。

It's over. 我地玩完喇。

Don't call me anymore咪再打比我..

There's someone else. 我有第二個喇.

We're not meant for each other.我地唔夾.

婉轉d既:

I need some time alone. 我需要一個人過一陣子。

It's not you; it's me. 問題不在你，係我既問題。

We're better off as friends.我地做朋友好d

You're too good for me. 我配唔起你。

You deserve a better man/woman.你應該搵個更好既。
