it was good but not quite there yet but keep working on it its a great start!!!

I really like what you have to say in this poem.

It seemed to flow a little better after i split the lines up some.

Like

" There is no room in your heart for me

This i know

For she was first

and it leaves me in the cold"
 

Hope that helped some... Write on!

I agree with Paul.  Splitting up the lines a bit would make more impact, and would also make it easier on the reader.  One point as I was reading through:

The pain of loving you tears me into
I wished I had a heart of stone

Do you mean that you are split in two, or that the pain tears into you?  I found this line a bit confusing. 

You could also play up more imagery of cold, stone, barren, etc.

Great job!

 I like the meaning behind this.  As the others mentioned, in the line "The pain of loving you tears me into" --  I'm pretty sure that was a simple typo and you meant "in two," as in "in half"?

Overall, good poem, but start experimenting more with your words, delve into your creativity and start pulling out some metaphors, and use some more description.  An example could be "I wish I had a heart like cold, smooth granite, "  which would not be the best for that rhyme scheme, but just an example off the top of the head about trying to be more descriptive.  

Also, you're using a very conventional rhyme scheme, and sometimes, in my opinion, when you're really trying to connect with readers, or have a poem that is very emotional to you sometimes you need to step outside the box and start experimenting.  The most important thing of all though -- keep writing!

 Definitely liked what you had to say, but the rhythm or something was a little off. I know, said before, but just wanted to add my second.

 I am going through something just like this right now and it is ripping my heart into pieces.  I did enjoy reading this, but it could use some works... I found a few...what I thought...to be errors.  However, keep it up.  I love reading raw emotion... I really get into it and can believe the poet.

 I really like reading raw emotion filled things like this. I do think it needs a little work though. Something is off. You have a good meaning behind it and many people can relate. I am actually going through this right now, so i know kind of how you are feeling. Keep up the good work.

 This peice, no matter what people say, was excellent. Let me tell you why. Millions of ladies go through this situation through there life. This is an issue that affects a person deeply. What you write is going to open the minds of a thousan minds and get them thinking if the relationship their in really worth it. Is it? I encourage and motivate you to keep up the good work. I'm not the type to be hung on the poems with the fancy words, or the extremely difficult analogies. I want to be the one to understand exactly where you're coming from. Keep up the good work and I promise you that you'll make it really far. Thank you.
