不挽留是你的借口
[bù wăn liú shì nĭ de jiè kŏu]
"Not holding back is just your excuse" conveys the idea of someone leaving or ending a relationship without trying to fix it. This name suggests a person who might feel hurt or left with an unfinished and unfulfilled feeling. In this context, there's some kind of reluctance to admit deeper reasons for separation or breakup.
