Which poem sounds better?

[Lucy]

Which one do you think is better? Thanks

When tears never fall,
And birds never fly,
When Winter never ends,
And children never die.
I will love you forever,
I know thats true,
Because I can't imagine,
My life without you.

OR

When tears never fall,
And birds never fly,
When winter never ends,
And children never die,
Our love won't last,
It will end too fast,
Soon enough you will be,
Just a thing of the past.

Thanks
