What might have been

I can not remember the title or band!! those are the only lyrics I remember AND I am sure it was a female singer... PLease help!!

Try Tracy Lawrence - What Might Have Been


Sure I think about you now and then
But it's been a long long time
I've got a good life now
I moved on
So when you cross my mind

Chorus:
I try not to think about
What might have been
Cause that was then
And we have taken different roads
We can't go back again
There's no use giving in
And there's no way to know
What might have been

We can sit and talk about this all night long
And wonder why we didn't last
Yes they might be the best days we will ever know
But we'll have to leave them in the past
So try not to think about

you rock! Thanks you!
