This song is about making mistakes and the regret you feel after making them.
But more importantly, the singer is in a situation where saying 'sorry' or 'forgive me' is not appropriate or maybe even unacceptable.
It's a bit philosophical in a way. There are some things you can't take back or apologize for. And it doesn't have to be something really bad or dramatic (like cheating). It can be a small thing.
The singer lost someone she really loves and there's nothing she can do about it...
