你若弃我不顾你必万劫不复
[nĭ ruò qì wŏ bù gù nĭ bì wàn jié bù fù]
The literal meaning is 'if you abandon me without a second thought, you will face eternal damnation', conveying a powerful threat or curse. The user may express strong feelings about betrayal and warn their ex not to take the decision of leaving too lightly. This type of phrasing can appear exaggerated or poetic.
