缺情缺爱宁缺毋滥是是非非物是人非
[quē qíng quē ài níng quē wú làn shì shì fēi fēi wù shì rén fēi]
Roughly translating to 'lacking affection but preferring none than low quality, everything remains but people change', conveys someone who has had a difficult time with relationships, valuing the quality of affection above quantity and observing how environments and things remain constant while people come and go or alter around them.
