Its simple

Roses are red, Violets are blue,
what you've done to me doesn't
compare to the damage Ive caused you.

Birds chirp, Dogs bark,
I'll forever be sorry,
for today we must part.

Cats meow, Humans speak,
You have no idea what I'd do
to have you here with me.

Some poems rhyme, others really don't.
I wish you would stay, and never have to go.
