冷冷淡淡今后都不管
[lĕng lĕng dàn dàn jīn hòu dōu bù guăn]
'Neither Caring nor Concerned in the Days to Come' - Suggests the individual feels indifferent toward the future, maybe due to past disappointments or having let go of someone/something. The tone here leans more towards emotional exhaustion or detachment.
