我视你如命你许他一生
[wŏ shì nĭ rú mìng nĭ xŭ tā yī shēng]
Translated as 'I regard you as my life but you promise him your whole life.' This reflects a bittersweet or sad situation where one person values the other deeply but sees them commit to someone else. It captures feelings of unrequited love and sacrifice.
