The UB40 song "If It Happens Again" is about a person who is frustrated and unhappy in a relationship. The lyrics suggest that if the same problems continue to arise and the person feels mistreated or taken advantage of, they will leave the relationship without any regrets. The chorus emphasizes this sentiment, stating that if the negative circumstances occur once more, the person will gather their belongings and depart without looking back. They won't take pleasure in saying "I told you so" to their partner. The verses address the individual's feelings of being obedient and enduring the difficulties they face in the relationship. However, they also express a sense of responsibility, blaming themselves for their current situation. The lyrics warn that if the same pattern persists, with betrayal and added insult, it is time to move on and leave the relationship behind. The song suggests that compromise has been exhausted and has gone on for too long. Overall, "If It Happens Again" conveys the message that there is a limit to how much a person can endure in a relationship, and if that limit is reached, they will choose to leave, seeking a better situation.
