Never That Simple

You know it's never gonna be that simple,
I love you, you love her;
You want me, I've moved on.
It's always some little thing, isn't it?

I saw you last night, just a blur on the street.
My green eyes met your endless blues,
You stopped and looked right back,
And for an instant, I felt you all around me.

The moment passed, I walked away.
I wonder what we could've never been,
What we never were and how it came to be
That I fell in love with the one who couldn't love me back.
