I didn't really get the impression of a rap like the other commentator because it had more of a smoothness to it. Rap usually has a consistent beat with some staccato moments in between to mix things up. This was pretty relaxed and thoughtful, and so I'll disagree.
I think you bring big ideas into your poem but the introduction is kind of clich� to me. I liked the comparison of the dry seasons to a lack of color, or perhaps, a lack of purpose in the writer's life. If I've read one "you've left me" poem though, I've probably read most of them. But I like how you develop the theme, even if it is a bit overdone. You relate being alone to a world of the black and white with no feelings, no color, no love. At this point I think the main idea has greatened to the natural need to feel loved by someone, anyone, to escape a self-destructive reality. It is a travesty when a person has no one to fall back on, as I believe everyone needs comfort eventually.
The fourth quatrain in a way says, "nothing else matters but the memories I hold in my heart," which is a dangerous way of thinking. I hope you don't personally feel this way as there is more to life than sharing love with someone, but I do agree it is a fundamental part.
It's amazing how you still hang on to the idea of this person in the fifth quatrain considering how much pain has been expressed in the previous ones caused by this person. But the care and love expressed to this person is relatable because I too am of an exposed heart.
This poem is sad throughout, unfortunately for the writer, but it is life, and I like how you're unafraid to express this part of life without restraint. I really like the question at the end because it reminds me of an ex of mine, and it didn't work out because of various things, and I often wondered the same question, "When you looked elsewhere, what were you looking for?" cause generally, dating other people makes you realize what you want, in a way, or simply being single for a while. I really enjoyed this poem.
