I'm not good at interpreting anything, but I'll give a shot on what I think THIS song might mean.
I think it means that he's saying how awful and demanding his girlfriend is.
For example, the second half of the chorus mentions that he'll never see this place again.
He might also be suicidal about his girlfriend's choices, 'and you'll go stabbing yourself in the neck'.
He loves her, but at the same time, she's a spoiled, boring brat who doesn't know how to love a man.
