To me, there's a lot of room for improvement in this piece. You try so hard to rhyme, and it really shows. I felt like, you attempted to find good rhymes, and couldn't so you just dealt with the ones you had and somehow found random ways to shove the words in there. It just didn't work for me. The flow broke a lot because of the rhymes, and it took away from the piece.
Your not worth a dime

`I do adore this concept ... "part-time" -- it's witty, a nicely picked metaphor for a heart that isn't fully in love.
It was okay, to me. It wasn't absolutely stunning, but it wasn't horrible either. Work on it. Definitely check on your syllabication. Overall, it was just ... mediocre. Try using more imagery -- express without just simply telling. SHOW the reader what these emotions you're attempting to express look like.
