死心塌地将情深葬在死海里百厌不烦地将置深情于死地
[sĭ xīn tā dì jiāng qíng shēn zàng zài sĭ hăi lĭ băi yàn bù fán dì jiāng zhì shēn qíng yú sĭ dì]
This conveys that someone is utterly determined to end a deep relationship, like sinking feelings into the Dead Sea. It also expresses the determination to repeatedly put an end to deep emotions with endless patience, as '厌' means tiring but it's used as a pun for '压', which means suppress. So this person might have given up on love due to repeated pain and decided to suppress any deep emotion.
