Wow! Your poem is welling with emotion; you have really captured the tone and diction that ensnares the reader's heart. Whoever the narrator (I know you wrote it, but the person telling the story in the poem) is, wether it be you or is just an omniscient view, has really connected with the reader.
I have just a few minor tweaks to suggest. I feel that in the 3rd line of the first stanza "can't" should be "cannot". "Hold" and "unfold" in the same line seems to have too many rhyming syllables. In the second stanza, 4th line, "come" would be better suited than "coming". Less syllables to say, easier on the ears.
I agree that the end could bne different, but it's your poem, end it what FEELS right.
