I really liked the first two stanzas, the rhyming and the rhythm worked very well in those two and they contrasted each other nicely, but the third stanza caught me off-balance. It didn't seem to flow as well as the others, and for me it just didn't work very well as a conclusion and ending to it, as if there should be something just to close it up...

Otherwise, first two stanzas really great, loved them, just... the third. Actually, after rereading, it's only the last line that bothers me, the first three lines work fine.

"You think me a treasure, bright and resplendent, and as nothing else could I ever be styled."
Gives a great, compact look at their relationship.

Amazing rhyme and rhythm. I love it.

That's beautiful, I loved it; the rhyming was excellent and flowed smoothly. Well done. :]
