爱了久了腻了倦了散了淡了不闻不问不想不念不在乎
[ài le jiŭ le nì le juàn le sàn le dàn le bù wén bù wèn bù xiăng bù niàn bù zài hū]
A poignant and melancholic expression conveying a cycle of relationships evolving through phases—deep love transforming into indifference and eventual disregard after growing bored, tired, then parting ways and becoming apathetic over time.
