他爱谁都不再与我有关
[tā ài shéi dōu bù zài yŭ wŏ yŏu guān]
'It Doesn’t Matter Who He Loves Anymore; None Is My Business' represents a feeling of moving on and becoming emotionally independent of a person's love affairs. In other words, when this phrase is used, it often means that despite the pain one may have endured before, now, nothing the mentioned person does or who he loves impacts oneself any longer.
