Hey, pineapple! It's been a while since I've reviewed anything, so I apologise in advance for how potentially ramble-ey this may turn out.
The poem was short but managed to convey the twisting wave of emotions that you experience as you fall in love with someone and then eventually move on. I really enjoyed how the contrast between each stanza was so stark, with each one outlining a different phase of the relationship and the corresponding emotions you experienced - with the first stanza talking about the narrator's disbelief in the very idea of love being flipped by this person, the second stanza covering the heady feeling of being with the person, the third stanza speaking of the relationship soured and quickly turned into a source for the narrator's grief, and the fourth one covering the process of moving on.
I enjoyed the simple, short way in which each line was written, which was very straightforward and blunt, pointing to the raw vulnerability that is expressed throughout the poem.
I really like when you likened the person to a rain cloud in the third stanza, suggesting how the initial feelings of love and affection darkened, like grey skies. Overall though, I think maybe some more imagery would be nice.
On the whole, it was a lovely read. Have a great day/night!
Happy writing! :>
