Hard Habit To Break

The speaker looks back on a relationship he took for granted. At first, he assumed his partner would always be there and acted as if her presence mattered little. After she leaves, he recognizes how much he cared. The emotional movement is from regret and self-blame to persistent grief: although he knows he should learn to live without her, he does not want to.

The phrase “you don’t know what you got until it’s gone” means that people may only appreciate something after losing it. Calling the former partner a “hard habit to break” compares attachment to a habit that is difficult to stop; “addicted” makes the longing sound powerful, though it need not mean literal addiction. “Living alone” while together suggests emotional distance: they shared a relationship but were not truly close. The “endless flight” in the night may express thoughts that keep racing when he is alone.

The song presents a painful mix of accountability and helplessness. The speaker admits he spread his love too thin and understands why his partner chose someone else, yet he also calls her departure a mistake. That tension may show how grief can make someone recognize their own faults while still wishing the loss could be undone. His repeated claim that he cannot go on sounds like an expression of distress, not necessarily a literal statement about what he will do.
