I like how this poem is written the rhyme is a little off. only the second stanza seems to be the only one tht rhymes.. all in all this peom is well described

"So maybe we dont always get what we want
And not all that glitters is gold
But I swear I'll never forget her
I'll never loosen my hold"

First line: "dont" should be "don't".
Shorten some of the wording so there will be a better flow here.

"Kuz she's the angel that fell from above
The one that taught me how to love
And even though she'd rather have him
The fact that she's happy wont make me dim"

First line: "Kuz" should be "Because".

Fourth line: "wont" should be "won't".

"So I'll just go on with my life
And leave her to hers
I'll keep writing my poems
Living my every verse"

Second line: I feel this line is very weak and you should reword it for better understanding, it just didn't hit me.

"Foever the darkest Angel
That's what I've become
And that is a title I fear
That I'll never escape from"

A powerful ending, I loved the concept and wording in this piece. Well-expressed feelings throughout the poem. 4/5 from me, just a few things you can touch up on.

Take care and God Bless!
