Standing

[Linda]

I don't know our love anymore.
It walked out the door before you
and left me standing in this room.
Every breath is our last together,
as stale as dust on the wooden floor
and our portrait, still on the dresser.

I like this, the simplicity of it, it has great potential but needs more in order to leave a lasting impression,
I would suggest adding an image of what you felt like standing in that room, what image depicts total
abandonment for you and go from there.  Then pick up with " every breath is our last together"
 
or maybe, our last breath together remains here
as stale dust on the wooden floor 
Hope this helps
Linda
