I was reminded of two Chinese slangs: 1. 智者不入爱河(zhì zhě bú rù ài hé) (The wise steer clear of the river of love.) (Smart people avoid falling in love. To love is to lose) 2. 恋爱脑(liàn ài nǎo) A Limerent brain (Someone who becomes irrationally obsessed with a romantic interest, often to the detriment of their own well-being, interests, or boundaries.)
