痴情喂了狗
[chī qíng wèi le gŏu]
'Feeling so deeply has fed the dog(s)' signifies having one's earnest affections wasted, unreciprocated, betrayed by loved ones - it can be heartbreaking when pure love goes unrecognized and misdirected into a void, or where only harm and loss result, much like 'feeding a dog' who can’t understand it.
