佢哋終於分手，結束咗三年嘅感情。

They finally broke up after having been together for three years.

嗰晚同大家分咗手之後，我先醒起自己未夾返食飯錢。

That night after parting ways with everyone, I realised I'd forgotten to pay back my share of the dinner check. (This would be a situation where one person paid at the restaurant with the understanding that everyone else would pay him or her back for their portion before parting ways.)

分手開元末，連年絕尺書。

We parted at the end of the Kaiyuan reign (circa 741), for years on end no letter passed between us.

[the/my] girlfriend wants to break up

不要開口閉口說分手。

Don't talk about breaking up all the time.
