But now we're like sleep
And the graveyard work shift
We just don't match up
^This is a different simile when it comes to poetry, but being someone who works graveyard I see what you mean here, sleep & working nights definitely don't go well together, kind of like your relationship you're speaking of & how it's not perfect.

Interesting write. Melancholic. Seems as though you're in the process of trying to figure some things out & your 'fox hole' is like your escape for the moment, your hide out if you will. This concept is thought provoking. Nice job.
