Come back

All I can do is think,
What happened?
When could I have changed it?
Will you ever come back?
I love you.

All I can do is think of you,
I love you,
My heart races for you,
Every time I see you,
Come back? Please?

But you won't I know,
I'm smart enough to know,
You aren't coming back,
I gotta give up,
But I love you... I can't.
