An inevitable change

The perfect one,
he knew, he'd found her
The one to cherish,
forever and after

In sickness and in health,
to stay forever, they vowed
Never let her cry,
while he's still around

But now they're stuck,
in the eye of a storm
And all their world
is falling apart

And nothing could stop
what's taking his life
Their fairytale of sorts,
would end in a trice

But it's not the physical pain,
that'll eventually fade,
It's the thought that he never
can protect the vow he made

In pain, he says,
when he's almost done,
We're two hearts,
but we beat as one.
