Discover the story of the song > Darlin’ – Houndmouth

The protagonist doesn't want to give their previous partner any more attention because they were not good to them. They feel like their ex-partner is cold-hearted and might end up hurting themselves if they keep going down that path without letting someone in. The chorus repeats a question asking why their ex-partner can't sleep at night and suggests that the colder their heart gets, the more likely they are to resort to violence.
