ever heard of
keeping your promises?
all these things that could have been
lie at your feet
sharp, jagged edges cut my skin
they slice at your heart
yet leave no scar
no evidence of emotion
no hint of regret
she trusted you to love her
and treat her as a guardian should
to let her live; yet here she lies
Sometimes I like to write a poem without a real structure, just words that express something more directly, without the need for rhyme.
I like how you start it out with a question; unless I'm mistaken, I think your use of "lie" is correct. I think maybe you could extend this a little bit. The concept of paradox leaves this open for more material; the nature of love can be very paradoxical, and you may come up with some interesting images. Perhaps you could tell a little bit of the story behind this; sometimes when I write a poem without structure, I like to tell a story with it.
It's good as it is anyway, but it seems open to elaboration. If you feel that you would like to work on this more, I think you should.
In this write you speak of how tired you are of all the broken promises. You say it cuts into your soul to leave no mark but it will leave you emotionless.
Just a few suggestions, please don’t be offended. You said “lie at your feet” This means not to be truthful at your own feet, I couldn’t help to smile. You must either say “laid at you feet” or “lied at. Your feet”
