假装遗忘比念念不忘更狠毒
[jiă zhuāng yí wàng bĭ niàn niàn bù wàng gèng hĕn dú]
This implies sometimes pretending to forget something can hurt more than continuously remembering. It conveys the complex emotions involved in trying to move on, while acknowledging the pain that deliberate forgetting may cause, which can be even harsher than constant longing and nostalgia.
