he puts his arm around
the cold shoulder she gives him
he smiles but inside hes dying
dying for what he cant have
her love

im hiding my heart of glass
I dont want you to see right through
because all you'll find in there is you
for six months you've been with him
but for years you've been with me
just break through my ribs and see

iv seen angels like her before
not as clueless as you pretend to be
cauterize the wounds made from your words
you know how i feel but you dont care
but i cant be mad
i could never.

im hiding my heart of glass
I dont want you to see right through
because all you'll find in there is you
for six months you've been with him
but for years you've been with me
just break through my ribs and see

broken, than fixed
a game of your whims
i love you one way,
you laugh at me in another
a game
im just a game

It's pretty clear as to what it's about. I, myself, love metaphors and shrouding the meaning behind them to make the reader think.

I like this though, the first stanza, especially.

"not as clueless as you pretend to be"

And that line, I enjoy.
I think I understand what it means and I like it because it has a hint of manipulation in the relationship you're describing.

It's good, your heart was poured out, I like it.

My criticism would be to use a thesaurus, sometimes....

I find that it helps to choose words that sound not just better or different...
but the way that consonants form... sometimes it gives a better feeling of what you're trying to say

Hope it helps.
