This song is a plea to give love a second (or third or fourth or...) chance.

The narrator is telling a girl, "I can see you've had your heart broken before. Maybe many times before. Other men have hurt you... but I'M not one of those guys. I'VE never hurt you, and I'VE never given you any reason to distrust me. I understand why you're skeptical and suspicious now, and I'm willing to take things slowly. But I want you to take a chance on me, because love is worth it."
