Pros: I love repetition, especially if it's a single phrase, which you use quite well in this poem. It's a very well balanced poem, following a structure of repeated line, new line, repeated line, etc.
Cons: The only thing that could be done to make this better is take out "this" in the line "this but i wont." It's an un-needed word that, in my opinion, slightly stunts the ending.
Overall: Very good poem, I especially enjoy how it ends. Good job :)
besides the few already-pointed-out grammar crap things, i adore this. its so easy to relate to (well except the polar bear obsession xD) and its so wonderfully written. in it you try to make it not a love poem by not 'telling', yet in a way it still is but im pretty sure that was intentional. xD still, amazing write. i love it.
in every instance of your, you mean you're. you forgot the apostrophe in won't and none of the I's are capitalized. The lack of punctuation makes me wonder if the polar bear obsession makes you laugh or if the love interest does.
Now that I'm done with the grammar, I like the self-consciousness of the poem, that you're trying to not make it a love poem. I like that the only reason to not profess your love is that then this would be a love poem. It's so bull-headed and cute.
A side note, the music, are we talking Backstreet Boys old, Kurt Cobain old, Devo old, Beatles old or Mozart old? Something specific here, instead of general could be nice.
It's a cute little poem about changing tides in a relationship written in a language of the heart..I like the conversational poetry that you created..Very nice, Julie !!
