Don't know if it's a poem but check it out
I'll stop loving you
When diamonds never sparkle
& flowers cease to grow
When thunder never echos
& rivers don't flow
When hearts no longer wonder
& hands are never held
When smiles are only memories
& hope is never felt
When trees no longer blossom
& stars refuse to shine
When God alone commands me
Then i'll stop loving you
It's not mine and i do not know the person who wrotte it but it is very nice and would like to share it just like it was shared with me.
