爱你之前我很幸福离你之后我很幸福
[ài nĭ zhī qián wŏ hĕn xìng fú lí nĭ zhī hòu wŏ hĕn xìng fú]
This means 'I was happy before loving you and I am happy after leaving you.' It conveys the feeling of being able to be content and happy in both pre-love and post-love life stages, showing personal growth and happiness independence from love.
