How?

How is it so easy,
I ask myself today,
To go on with your life
To turn and walk away.

Don't you ever wonder
How different life would be,
If she hadn't come along
And you would have stayed with me?

Our love was strong
Our intentions were true,
Every day inseparable
That was me and you.

She's living the life
That should've been mine,
I've tried to convince myself
That everything is fine.

I'm better off without you
This much I know,
We used to be best friends
Now it seems you are my foe.

What's done is done
I can't change the past,
What we shared so long ago
I thought would always last.

I can't help but think sometimes
About how it used to be,
I won't stay mad forever
But you should have been with me.
