There is a simplistic sort of elegance to this... I liked it, especially the "but I have him, and you have her" and "I love him, not you, and you love her, not me". Like I say, simple language, but effective in every sense of their meaning. Good job! :)

Aww, this poem is sort of bitter sweet. I kind of feel sad reading this, because I can really relate to it. It's really beautifully written.
