I agree. It's about a guy who is cheating on the one he cares about. "the warmth is slowly fading" because he's watching her after what he's done and doesn't feel the lust he felt before. He's realizing the magnitude of the mistake he made, and is wondering if the one he cares about would take him back if she knew what he had done. He knows he's not doing the right thing, but "there's always someone...hanging on" meaning that he can't do right by the person he should be obeying because there is always someone else to satisfy. "your tears don't fall they crash around me" shows the impact of the loved one's dispair on him. He knows that she knows what's going on, but he can't seem to make the right decision. He's done it before and can't reform himself without help, he's just not sure if she'll be there to forgive him again.
