Amy Pearson - Wish I Was Her

Always knew when we said goodbye
It wouldn't last forever
Alway thought that I'd run into you
And we'd get back together........

Now you're here
Just like I imagined
Never once did it cross my mind
That you could move on.......

You've found someone
It breaks my heart
Cuz you're so in love

[Chorus]
I wish that my touch
Makes you smile just like that
And I wish that I had you
the way that she has
Cuz I still remember the love
I left behind
Oh I wish I was her
And you were mine

I think somebody's try'na to talk to me
But I can't hear what they're sayin
All I can do is stare at you
I dont even know why I'm stayin
Never thought, I'd cry to see you Happy Its Just I
Thought that your happiness
Was right here with me

I know were through
