This poem was full of great questions and imagery. I just wished the last stanza flowed and rhymed like the rest. Here's my suggestion to make it follow the beauty of the poem you've penned (and this is just a suggestion, because your poem is amazing thus far)

To your last stanza I would do it like this:

When your heart aches for him alone, your former sadness breaker.
But you know it can't come back when he turns into the taker.
When you blame him for your heart, burned to the third degree
When you hate that you can't hate him though he's done so many things

Now my friend, you're just like me.

Just a suggestion...

Its difficult to move on when there is no one who understands what you are going through. and the pieces to pick up are shattered too small.

This is really a great write. Beautifuly done.
