WalrusMan is right about this song. It's about the end to a relationship. The divvy up the wine part shows that they are placing things into categories of what is his and what is theirs. That's the end to any relationship really. And I do think the tone he has show he does accept this. I mean, it'd sound much sadder if he hadn't, or more angry.
