On Leaving

I know I have no right to you  
for you are yours
and so you leave.  
I'm left in darkness loving,
my eyes upon my fading view  
of your confusion taking you
away from me to something new,  
forgetting who would trade his soul to
hold one glimpse, one moment true  
of lovely predeparting you.
