I find it rare to see darker poetry these days, but this one is awesome. It gives a sense of deserved hatred towards someone that has done wrong to you. To me, this poem speaks of someone who took advantage of you despite your kindness, and is now realizing that there is no hope for forgiveness. Very amazing piece.
You're very welcome. I am in love with poetry, and am a poet myself, so it is slightly easier to grasp emotionally inspired metaphors and analogies. If you'd like, you could check out some of mine and maybe get some ideas.
