An Appendage

Like the arm
you can never get comfortable
when trying to sleep
with my fist against my mouth
so you won't hear me scream
"When did we become leftovers?"
too little to save
too much to throw away?
my head used to fit perfectly
under your chin
now it seems I don't fit
in the bed
the tangle of sheets confuses me
I've put my pillow on the floor
we can no longer share
the same blanket, curled tightly
around your feet, my nakedness
is cold beside you, beneath your gaze
a look, not like I was invisible
like it wouldn't matter if I were
like the appendix you never think about
until it's got to go
I have to leave
I wonder if you'll miss me
or if I'll leave a scar
