我只希望你过的没我好
[wŏ zhĭ xī wàng nĭ guò de méi wŏ hăo]
It's an ironic or sarcastic expression that might be used when someone wants to show they do not wish anyone bad but express their pain after a breakup or similar experience. Literally 'I only hope you live worse than I'. But often, this is expressed with sarcasm which means that person wishes someone well.
