Fourth Edit: Hometown

[lyon]

Great edit! You really cleaned up the narrative and intention, I can see the poem much more clearly now. 

I
I'm sorry. I love this as the beginning. It carries so much weight and sets the whole tone for your poem. I would give this its own section. 

II
It was best to leave while you were asleep. Killer line! says so much with so few words
The moonlight tried to give me solace, 
but its pail arms failed to couldn't touch me.
I even stopped, // I stopped once
surrounded by darkness, (and moonlight that couldn't touch me?) 
that in front me me, my future,
that behind me, my feelings
for having to abandon you they way I did.
“Don't look back,” my mother used to say.
For once, I listened. 

III
For the first year, I felt like your pet,
who wandered away to find its deathbed. // who wandered away out of curiosity/ignorance, only to find its deathbed 
I imagined you might have felt the same. Adding "might have" here may increase the feeling of distance. I like this line very much but I'm not sure it belongs here. It may work better in the middle stanza. 

When I returned,
you looked more beautiful then before I left; "more beautiful" is quite generic, maybe try "glowing/radiant/shining"
this is when I began hating you. // So I began to hate you.

So fun to see how this is developing. I think the poem is strongest at the beginning and the end, the middle stanza is just beginning to really find it's form. Perhaps play around with where you've put lines and again, pay close attention to the imagery you're selecting.
