Lyric discussion by emilyak 

"and I think I could leave your world, if she was the better girl. so when we died I tried to bribe the undertaker. 'cause I'm not sure what you're doin' or the reasons."

Just going by personal experience here... It's a feeling you get when the man you love betrays you with another woman and you're just perplexed and constantly bombarded with the "what does she have that I don't" thoughts.

At some point, you'll realize that said "other woman" is lacking in many ways. You'll say something along the lines of "I could understand if she were better than me/could offer you something that I couldn't". You'd be willing to release the man if you were sure the other woman could make him happy. Why hold someone if you make him miserable?

Bribing the undertaker would be doing lots of things, some desperate, to try to analyze or seek why things went wrong, but you'll always come up with the conclusion that you'll never understand what was going on in this man's mind and why he did what he did for seemingly no reason at all.

A little bit of bitterness with finally a little bit of "someday you'll see what you lost" thrown in.
