Loneliness

The lyrics describe a relationship in which one person feels hurt and alone, despite the repeated mention of happiness. The speaker seems to blame the other person for being self-centered and looking at other girls. Repeating the same lines gives the feeling of being stuck in a painful thought, with little movement toward comfort or resolution.

The contrast between “happiness” and “loneliness” suggests that joy may feel incomplete or even connected to being alone. Saying loneliness “chilled my world” is a metaphor: emotional pain makes life seem cold, distant, or lacking warmth. The accusation that the other person was “only thinking of yourself” points to neglect, while “looked to other girls” may suggest flirtation or divided attention.

The lyrics do not explain exactly what happened between the two people, so the speaker’s accusation is only one side of the story. The repeated question, “How could you guess,” may express disbelief that the other person failed to notice the hurt, rather than a literal question. Overall, the song can be heard as both a complaint about a careless partner and a reflection on how happiness can feel tangled up with loneliness.
