爱你到骨髓却被你挫骨扬灰
[ài nĭ dào gú suĭ què bèi nĭ cuò gú yáng huī]
'Loving you till my bone marrow, yet crushed to ashes by you'. It implies that they were completely devoted and passionate towards someone, even giving more than their full love; but in response they faced a very negative treatment and suffered emotionally. It symbolizes betrayal in a profound relationship.
