你若不爱我就不留
[nĭ ruò bù ài wŏ jiù bù liú]
The direct translation is 'If you do not love me, I won't stay'. This conveys the idea that if someone feels not appreciated or loved back deeply by the other person, he/she would rather walk away or move on instead of sticking around just for the sake of it. It shows confidence as well as strong-mindedness.
