Growing Pains

She told me,
hearts don't break.
The ache you feel
is growing pains:
too much love,
pumping just like blood.
Once we give birth to love
it never dies.
Like a child,
the first is never undone,
only added to.
And I wonder if
she's right-
if those who have
lost the most
have also
loved the most,
until their heart-
so full-
must burst.
