What If (Film Version)

Here I stand alone
With this weight upon my heart
And it will not go away
In my head, I keep on looking back
Right back to the start
Wondering what it was that made you change

Well I tried, but I had to draw the line
And still this question keeps on spinning in my mind

What if I had never let you go
Would you be the man I used to know
If I'd stayed, if you'd tried
If we could only turn back time
But I guess we'll never know
We'll never know
