tsuwm, encouraged by your bravery, I'll post something original too. (This was an exercise from my writing class - apparently a sestina, definitely the most taxing poetic form I've come across in English)

Keeping Together

My sun, my moon, my stars - you are the light
that gilds the summer days within my heart.
I do not know or care if this is right.
I'm more concerned - and have been from the start
of this our love - by twisted Fate, that might
find cruel ways to tear our souls apart.

For in the briefest hour we spend apart
my senses fail, my spinning head is light.
I lose my very self, till with a start
I know your voice or touch and all is right.
The storm subsides - your presence soothes my heart
to rock in sweet content as infants might.

Do you recall - I rather think you might -
we swore that we would never be apart?
Then, from the fading of the evening light
until the sun called the new day to start,
I grasped your tiny hands and held them right
where they could feel the trembling of my heart.

Do you remember how it beat, that heart,
and pushed against your touch with all its might?
How you leaned close, how lips barely apart
breathed soft with love and stars and laughter light?
And then we kissed… It was the start
of my belief our love would come out right.

But now it seems you'll exercise your right
to tear the bleeding entrails of my heart.
The hold I have upon you is too light -
you'd leave, and rip our close embrace apart.
Your soul succumbs and knows another's might -
our game's played out so yours and his can start.

I cannot understand. When did it start?
Just when and how was it you seized the right
to play these deadly tricks upon my heart?
I thought we loved as true as any might,
but I was wrong, and now that we're apart,
my shattered dreams will never see the light

Yet in the cold dawn light, when I wake with a start,
though it might break my heart, I will not prove you right.
E'en though you said I might, I will not fall apart.
