Don't ever want to lose you

I am
so afraid
to lose you-
not the "we go
into the store,
you go this way,
I go that way"
half-hour later
I'm wandering around going
"where the heck is he?"
I'm talking
never be able to talk
to you again,
never hear your words
to me again,
never to be held
deep in the night
while the night rages around us...
How do you tell
someone
what they mean to you?
What they've done for you?
That being apart
isn't an option?
That I'm scared to death
with just the thought
of not having you
in my life-
You are the very air
that I breathe
without you, I'm only
a mere shell
just existing-
you have given me
a life worth living
for that I thank-you
for that I love you
even more with each
passing day...

My husband was born with a congenital heart defect, I wasn't with him yet for his first 2 open heart surgeries but I was with him for his 3rd and latest. This poem came to me when I went in to pre-op to give him one more kiss and hug and a good-bye, I was terrified thinking of course the worse thing that could happen and what kind of good-bye could you possibly give someone that means everything to you. He has given me a life I never thought would be possible and a simple good-bye just wasn't enough. What do you tell someone like that?
