The Human League's song "Never Give Your Heart" is about the fear and caution one feels in a relationship, particularly when the other person seems unreliable or unsure of their feelings. The lyrics convey the message that it is important to protect one's own heart and not become too invested in someone who may eventually leave. The protagonist of the song is pleading with their partner not to hurt them or leave them. They express frustration at the mixed signals they receive, initially being told that their love is real and then being told that the partner is unsure. The protagonist feels that all the heartache and emotions they have shared mean nothing to their partner. Despite the confusion and lack of commitment, the protagonist still holds hope that one day their love will be reciprocated and everything will work out. They dream of a future where they will be together and the partner will understand their significance. However, the central message of the song is to be cautious and protect one's heart. The refrain "Never give your heart to a runaway" emphasizes the importance of not investing too much emotionally in someone who may easily leave. The protagonist realizes that they cannot make their partner stay or change their mind, and it is better to save some love for themselves for another day. Overall, "Never Give Your Heart" is a cautionary tale about the uncertainty and sometimes transitory nature of relationships. It advises listeners to guard their emotions and not to become too entangled with someone who may not truly value or appreciate their love.
