既然不爱就走开
[jì rán bù ài jiù zŏu kāi]
'If You Don't Love Me Anymore, Just Go Away' is rather direct expression conveying an attitude of not clinging on unreturned love. It conveys emotional honesty and strength in letting go, suggesting readiness to confront reality, however harsh, and preferring straightforwardness over pretending to avoid unnecessary pain.
