Please review my poem. I need constructive criticism?
Written by a 14 year old girl
Once upon a time, I believed in love
I believed in happiness and trust
I believed that no one would ever break my heart
Until you came along
Until you walked into my life
I gave you my trust freely
And you used it to get the best of me
And as I sat there, I had no idea
That you would soon grab a hold of my heart
And tear it in half and shred it to peices
And as you destroyed me
I watched as you went to her
And I watched as you both held hands
And I saw as you both smiled
And then I realized
That you were the one
You were the one who walked me through life
You were the one who made me love myself
You were the one that made me believe in true love
You are the one who makes me walk through life
You are the one who makes me hate myself
You are the one who makes me believe in true hate
And yet, as I watch you from my corner
I still love you.
And yet I hate you.
But I can't live without you.
I wrote this poem when I found out that my best guy friend started going out with a girl who he only knew for 3 days, instead of me, who loved him, who knew him for 3 years. He is still with the same girl; but when I was writing this, I was very angry. I still feel the same way, but different. You know?
