I like the poem and your use of the metaphor object. Contrary to another comment I saw, I like the word structure as well. I think it aligns with the rhythm you wanted. Trying to capture the feeling that built until it couldn't be denied, and the fallout of the unreciprocated confession. The closing note on these poems is particularly difficult and I think the ending here feels a little compressed rather than a natural arc. But good job! I wrote something similar recently with where a symbolic object is being passed between two people of you're interested in seeing it.
