I have a poem with a similar subject matter.
Its written from my ex boyfriends point of view,
the last stanza is me telling him how it is,
heres a the few lines,
~'Now Sweetheart,
~All I Ever Wanted Was You In My Arms,
~The Way You Giggled Our Last Love Song.
~Now Your Gone,
~At Long Last.
~Stolen Chances,
~I'm Afraid Our Time Has Passed'.
If you get a chance you should check it out.
Anyways, back to yours, its a great poem, and its empowering when you get over someone like that.
