我错过了很多后来你守护了很多未来
[wŏ cuò guò le hĕn duō hòu lái nĭ shŏu hù le hĕn duō wèi lái]
Translating to 'I missed a lot, later you protected a lot of the future,' this implies regret over missed opportunities balanced against appreciation for ongoing support. Perhaps acknowledging that though one made errors, the partner (or other person) helped secure future hopes and aspirations.
