Because

[Wjames]

Because the air is sick and dark,
dense with disease. 
My lungs will blacken and bleed
long before yours; you are accustomed.

Because I am the bird you left in the cave
with no one watching. This is interesting.

Because I reached out to touch your arm,
and your skin felt like leather.

Because sorrow is crawling into every corner of me I think this might be better without 'of me' - without those words, sorrow is still crawling in to every corner of the narrator - but also everywhere else as well.
like perverted scarabs. 

You woke me with the kind of kiss
that can't be ignored, the kind
that asks questions
I thought I could answer.

The clouds assemble 
and begin their grim work.  

Because you cannot see the ink in the air,
and I am tired of being your beauty—
these are the reasons why I think this line should be cut, the because's say it already.
I am going back to sleep.

Hey Lizzie, I like this one - the scene is clear with the spurned advance, but the disease, stranded bird, and stormclouds add some interesting images.
