I think this song is about being with someone who seems to be so much better than you.
Someone that stays with you when you come stumbling home drunk and starving after a bad night, and in your sore mood you wonder how they can be smiling and singing when it feels as if your world is peeling away. Almost as if they're insensitive to your pain and the things you're going through. So you begin to push them away.
I think when the duet comes in to say "I don't want you... I don't want you anymore", it's signifying that both sides of the relationship are fed up with one another's behavior because no one wants to really be a crutch time and time again for someone that digs themself into a deeper pit, and if you're the one digging, more often than not you want empathy and someone to carry you instead of singing Spongebob's "F.U.N." song.
