Please Read and Comment on my Twilight Poem?

I just wanted to know what everyone thinks about my poem I just wrote, I haven't been able to write in like 4 yrs. so it might not be the best, but it works for right now. Please let me know if there is anything I should change.

Please no rude comments, only constructive criticism please (it's a poem for Twilight)

Bella’s Protector

How lovely is your innocence, my sweet Angel
I shall not take that away
But, if you should ask me why
This I would tell you, with truth and despair
I am not like others, don’t you see.
My skin is marble, my body like concrete
I am filled with venimous poison
I dare not touch your fragile skin
Fore if I do you would surely die
Oh how I wish this wasn’t so
Your beauty is undeniable
So mesmerizing that it feels like
Heaven when you’re near.
Your essence pure like a moonlit night
It radiates off of your soul
I cannot live without you my love
But I shall not take the chance
My love is selfish this I cannot deny
But, I must be the strong one, for your sake alone
Remember this one thing, my Bella
I cannot promise my love to you, but I will
Always be your protector
