爱情似梦不爱就醒
[ài qíng sì mèng bù ài jiù xĭng]
With the saying 爱情似梦不爱就醒, it expresses the view that love can resemble a dream and just like a dream that ceases upon waking up - if there's no more passion between people then they should move on rather than staying in a dead relationship. Represents realism about emotions in relation to romance.
