Some realtionships are not meant to be, yet it's so hard to say good bye. Sorrow for never saying goodbye when you should have said it long before the lies and the hurt. That's what I read in this piece. Also, do I detect a hint of pride? What about that ungiven rose? Why was it never given? And sorrow for never saying goodbye? This whole piece is about goodbye, isn't it?
The last lines loose the flow, though, I think. Sometimes, although rhyming is nice, it gets in the way of the flow and the rhym takes charge of the poem, instead of the feeling being in charge. Does that make sense? You wrap your feeling around the rhym and loose conection with the feeling.
Or something like that... I wouldn't worry about rhyming the last two lines but concentrate of sylables and flow. Other than that, I like it. Az
