What went wrong?

How did it come to this?
Why aren't we friends?
We've known each other for so long
So how could it have gone so wrong?

I thought I knew you
I thought I could trust you
So what went wrong?
We've been through so much yet we've always been strong.

Now I can't see a way to live
Without you in my life
I've made so many mistakes
But believe me, I never meant it.

I thought we'd always be together
I thought you would stay.
So what went wrong?
To make you walk out the door
And out of my life.

What about the love we shared?
What will happen now?
You gave me so much pleasure
Yet caused me so much pain.
