The song is about a man who loves this women so much that, although he knows she is lying he can convince himself (through minimizeing and denial) that she is telling the truth. He doesn't want to be without this love in his life no matter how cruel she is to him he wants to find that reason to believe and stay with her in his happy little life of blind denial. Most likely because her cruelty is too hurtful for him to face and bare.
