I think this song is about a relationship that is falling apart. I would say that the guy walked out on her (literally, it seems, from verse two), however, the final refrain:
Please sleep softly
Leave me no
Please sleep softly
Leave me no room for doubt
Please sleep softly
Leave me no
Please sleep softly
Leave me no room for doubt
leaves me to think that she is suspecting him of cheating on her, and she is pleading with him to not give her any reason to believe that this is true. The first verse is her thinking about the relationship; she stays with him because she either feels comfortable with him because they've been together a long time, or she just views him as a 'safe choice', but she doesn't want to put up with his actions and considers breaking up with him.
The mistake they refer to could either be the relationship they're in, or the man's affair.
