Very touching piece, the repetition is well used here, especially with the way it appears in the last stanza - that really impressed me.
The rhyming was a good idea, it gives the poem a very nice structure. All in all, I have to say the structure you used was my favorite part.
The wording is nice, though. Nothing wrong with it, and it seems to flow pretty well except I always trip over the last stanza. Somewhere among "Would you mind loving once more" you lose the beat and it steals a lot from the whole poem.
