I love this! Love the repetition and the description "Dull, lingering, unmoving in its own kind of glory
An empty hole that's old but still feels ripe"- I could almost feel the pain you were describing as I read that. The flow is nice and the rhymes work well, I found them to be quite subtly placed (truth be told I didn't notice for the first couple of stanzas), but they definitely help the poem to flow well. Excellent emotion, excellent feeling, love this!
