Are you looking for the words they *say*, as opposed to the lyrics of the song?
You can find the lyrics here:
http://www.azlyrics.com/lyrics/castingcrowns/slowfade.html As for what she says, I *think* he yells "It's not all about you" and then she says, "You know what, it's not about you. {business!} A need? 'I need another woman'? You make me sick, {Roy}" and then he says, "You make me sick, too".
(stuff in {asdf} is stuff I'm not sure of)
At the end, the guy says, "Well, maybe they can do without me this time." (Which, I guess, shows that the chaos going backwards the whole song will now not happen.)
Is that what you needed?
