Love this song. "It took time to realize and I never saw it coming / Forgive my lying eyes / Gonna give you all or nothing". I took this to mean that she cheated on him when she was younger and perhaps didn't think she was serious about him. She realises the extent of what she's lost afterwards and wants to give him all of her but he doesn't want her back hence she wishes she could change his mind.
