There is so much I like about this verse it has such a melancholy feel about it which is very much in keeping with the subject and the month you refer to here. Also, I loved the layout...the only think I could sugguest about that is to separate this line from the rest....Come back to me! I just think it should stand on its own for better emphasis?

But I exhaled the chill
in my chest to find
that I lost you amidst
the silence of winter
nights.

This part was very creative I thought....rather than just say a long sigh you were very artistic in your description.

I also thought your ending was perfect...very nice write from you.

I don't know but i feel i have read this poem before. you should write some more. i enjoyed reading it
