Perhaps slightly more cryptic than you're looking for but I always find Richard Thompson's Dimming of the Day to be a gut wrenching break up lament. Beautiful tune as always, here are the lyrics:

This old house is falling down around my ears
I'm drowning in a river of my tears
When all my will is gone you hold me sway
I need you at the dimming of the day

You pull me like the moon pulls on the tide
You know just where I keep my better side

What days have come to keep us far apart
A broken promise or a broken heart
Now all the bonnie birds have wheeled away
I need you at the dimming of the day

Come the night you're only what I want
Come the night you could be my confident

I see you on the street in company
Why don't you come and ease your mind with me
I'm living for the night we steal away
I need you at the dimming of the day
I need you at the dimming of the day
