I'm leaving you

[Desrei]

I'm leaving us my love,
my reckless entanglement,
my fucking mad, headlong descent
into today.
You swore we'd die entwined
in each other,
loving each other.
Give me a chance you said,
to prove my love, you said.
Ha! you had me there,
I didn't ever see this coming,
This cold, this freezing cold,
I'd have taken hatred any day.
Didn't I deserve that,
at least that?
Didn't I, my love?

I will start of by acknowledging what you intended with this poem. You want it to "scream" out your frustration towards a girl who mistreated you, or disappointed you in a grieve way. Although I am not a native English speaker, and I'm still a novice poem writer, I can give you my perspective on your writting; what I think of it, what bothers me, what could be done to improve it.

Firstly, it doesn't read out as a poem for me, when I try to read it, I start rapping. It reminds me more of rap lyrics than a poem. With a few tweaks it could actually be a good rap song. Seriously now, I underlined some parts of the poem that particularly bothered me.
For the first underline I could be wrong, but you can't leave "us", and it would sound better as "I'm leaving you" (In my opinion). It would also connect with the title and just start it off much better.
I underlined "fucking", because this is the first part that made me think of the poem as a rap song. I am sure that swear words are used in some poems, but I have yet to see some without searching it directly on Google, and I am also sure that there is a reason as to why they are so rarely used.
After this we have a few examples of "over-repeating". I don't mind repeating in a poem, but in your case, it completely shifted the flow of the poem. It made the poem seem clumsy, thus making it harder to read as a poem, making me rap it out.
Lastly, what exactly "didn't you deserve"? If I had to gather that information out of the poem, it would be "I'd have taken hatred any day". So you're trying to say that you at least deserved to take hatred any day? I'm sure you did not mean it like that, but the wording is quite deceiving.

Overall, I think you have a lot to improve on this poem, or take much more things into consideration while writing your next one. I definitely haven't gathered all the faults of your poem, but I hope I'd got some that others haven't yet, so that I could at least be somewhat helpful.

P.S. You really need to try rapping out your poem, it goes through quite smoothly with a good beat.
