Standing

[Richard]

Hey Youi,
I like the overall idea here. I do have some suggestions about the wording though:

I don't know our love anymore. -For some reason the word "love" doesn't strike me as right. What if you change "our love" to "us"?
It walked out the door before you -If you do what I suggested above, then this line could read something like "What we used to be walked out before you"
and left me standing in this room.
Every breath is our last together, -This line feels like filler, and I would actually suggest removing it. I know this goes against what everyone else said about expanding this poem.
as stale as dust on the wooden floor -If you removed the previous line, then I would replace the "as" here with something like "we were"
and our portrait, still on the dresser. -I would suggest removing the "and" here.

I do agree with what the others said about expanding on this idea and giving more images/details. However, I think keeping this short is a valid option as well.

Cheers,
Richard
