"The bullet pierced straight threw his heart.
It didn't hurt him so bad.
Because it was already torn apart."
That's where I really saw the most creativity and uniqueness. It was a fresh sentiment - one that I hadn't run across before. Furthermore, this is one of the few places in this poem that you did something more subtle and refined than stating the obvious.
Truly, many, many people have written what you just wrote about. Most of them end up sounding exactly the same. It's your job, as a poet, to try to say things that many people may feel, but few people are able to express. For example, instead of saying something as simple as "she really still loved him," you could use words that show why HER love was so different from the rest. Take it from -stating- to -illustrating-. Describe her love.
As for the form - there are a few small grammatical errors, like "hear" that should be "heart," and "your" that should be "you're." Those are easy to fix, if you give it a close read-through.
My big pet peeve about this particular poem was the periods. Every line. Doesn't need. A Period. If you wouldn't put a period in, if this was all written out like a story, then you don't need one there in the poem. At the very least, use commas in the middle of thoughts, and continue the sentence down through where the thought ends. Periods just break up the thought into little, undigestable chunks. Sounds appetizing.
I hope some of these comments helped. When it comes down to it, you are the poet, and you make the decisions. Good luck writing!
