Constructive Critism

Can someone give me feedback on this poem :)! Thanks!

Mama told me to never try to pick up broken glass
You'll get cut picking up the pieces
I guess she hated when she saw me with him
His arms sometimes like a straight jack
Coiling around me like a Boa Constricter
Squeezing me so tight he crushes my back bone below his hands
He constricts me and,
Comforts me
But the very same arms are entrapping me
Entombing me in a half-thought out dream
By reminding me how much he needs me
His shattered dreams and non-existant self-confidence
Rendered him child-like and awkward
Like Mother Theresa I tried to nurse him
And fix the broken pieces of the stain glass window he called his soul
The window grew to great and dug deep into my skin
Cutting, and amputating my own body
And I use my pain like a noose to hang
Hang in his prescence over his bed
Like a dream catcher
To catch his broken dreams
I'm giving him my essence my very being
And I can't help trying to harbor the injured wings of a fragile robin
Because I am an angel
Opening my arms wide to him
Like I'm on a crucifix
Trying to give him everything---
I'M GIVING MY ORGANS
I don't need a lung
So I'll give it to you so you can learn how to breathe
Without the self-doubt and loneliness in every breath
I'm giving you my heart so you can learn to live, truly live
And try to succeed
As I bleed
I bang on prison bars
Driven by my own self induced sentence
Call me a masochist

He holds me captive gently
Builds his walls on the sunny beach of broken promises
And low self-esteem
I don't know what it feels like to be whole anymore
For every night I lay battling with you
It stabs me in the back
Every cut
Every scar
Every scratch,
Self-driven---
When you said you hated yourself
It was like a dagger that sliced me open
And I was vulnerable and broken
Well at least we're living dying together
Like zombies feeding off our own poisoned flesh

I can't help that I love you
I wanted to lift you up on a pedastool
And marvel at the great statue of my solid servitude
But you didn't understand
You're words like a butterfly knife creating a Chester Cat smiling on my scowling face
Another knife carving empty holes into my soul
As you suck the spirit out of my helpless body
I cannot get out because this was in a way my fantasy
A fallen angel
But I was not equipped to treat his razor sharp wings
I cannot scream for help
I'm the one cutting my own vocal cords
Leading his sharpened finger nails to dig into my neck

Tell me why I'm so quick to love broken boys
When inside I'm a weak column slowly crumbling
And I can hear the falling stones echoing
Like shockwaves
Sending sadistic messages to slay to the sanity of the man who is unknowingly breaking me
The falling stones create tomb stones
Now I am dead reveling in my own bruises
Thinking I could love away your scars
I have only created iron clad bars
But I would rather be broken with him
Then lonely
I am a victim to my own halo
But angels are nothing like robins
You cannot doctor things you don't understand
I am my own patient
My medication being suffering
Slowly sedating me to a skeleton of numbness
My body left sucked dry and covered with lacerations
Indentations of my sanity being clawed away
I am a walking skeleton
Who will gladly lock arms in a marital grave
If there was a chance of "saving" him
I am martyr
I am his Jesus
Atoning for his sins
I am a girl who loves broken boys
