"On To You" lyrics

I noticed today
You're looking great
Wearing a big smile
On your face

A new pair of shoes
Well, isn't that cute?
I wonder where you're
Running off to

It's not the first time
You've left me behind
Coming home in the middle
Of the night

You climb into bed
What's on your breath?
You say it's just a night out
With your friends

But I'm not stupid

You never hid it well
I could always tell
You never thought I knew
But I was on to you

I should've known
You weren't alone
I heard his voice
On your telephone

Called you at home
Could tell by your tone
Plus I heard his voice
On your telephone

And I'm not stupid

You never hid it well
I could always tell
You never thought I knew
But I was on to you

You made me look like a fool
But really I'm cooler than that dude you're doing

You never thought I knew
But I was on to you

I was on to you
But I was on to you

All white little lies
And all of the pain
And all of these clues
Will finally explain

What you've done
Is out in the open now
And I just wanna say
That I'm not stupid

You never hid it well
I could always tell
You never thought I knew
But I was on to you

You made me look like a fool
But really I'm cooler than that dude you're doing

You never thought I knew
But I was on to you
