Finding air where matter once was (poetry)

Formerly you,
traced the knuckles of my fingers
slowly,
as though trying to unlock some mystery

Previously there were
sleepless nights, trying without success to answer
all of the questions our bodies were asking.

Once upon a time, I
rolled over to your side of the bed
while you showered,
just to hold the heat there.

That was
not that long ago.
When I could reach out for you and grasp more than just
the shadow of where you used to be
