Claude Francois - I know

I know, but it's hard to believe
I know that this time you will leave
We've tried so many times before
But now I must open the door

I know there is no more to say
I know I must go on my way
I know I should hide all my tears
I know I must face lonely years

And though I know, I know
I just can't believe
Someone else is holding you
For though I know, I know
That I have to leave
What is left for me to do ?

It's wrong to be envious of
The one who has taken your love
I know that I should wish you well
I know that my life will be hell

And though I know, I know
That I call my friends
With my endless says of war
For now I know, I know
You will leave my life
And you're all the life I know

I know I should try to forget
I know that it's wrong to regret
I know I'll remember the dreams
I know just what losing you means

And though I know, I know
I just can't believe
Someone else is holding you
For though I know, I know
That I have to leave
What is left for me to do ?
