There is a country song with a female artist and it is about where were you when I was alone who is it?

can you give us a little more?

Maybe it's "Where've You Been?" by Kathy Mattea??:

Clair had all but givin up when
when she and Edwin fell in love
she his touched his face and shook her head
indisbelieve and sighed and said:
"in many dreams i've held you near
no at last your really here"

Where you've been i've looked for you forever and a day
Where you've been i'm just not my-self when you're away

he asked her for her for life
and she became a sales mens wife
he was home each night by eight
but one stormy evening he was late
her frightened tears fell to the floor
until his key turned in the door

Where you've been i've looked for you forever and a day
Where you've been i'm just not my-self when you're away

they never spend a night apart for sixty years she heard him snore
now there in the hospital on seperate beds on different floors
Clair soon lost her memory, forgot the names of family
she never spoke a word again, then one day they wheeled him in
he held her hand and stroked her hair, in a fragile voice she said

Where you've been i've looked for you forever and a day
Where you've been i'm just not my-self when you're away
no, i'm just not my-self when you're away
