不是你不好只是他不爱
[bù shì nĭ bù hăo zhĭ shì tā bù ài]
The English equivalent is 'It’s Not That You Are Bad, He Just Doesn’t Love'. The name suggests the user is trying to convince himself/herself or console those who are dumped in the face of love failures. In other words, there's nothing wrong with the victim but just simply not loved anymore by another side
