I did the worst thing of all
The one thing I was taught
To never do
I knew better
I think if I had to bet
It'll be my biggest regret
I'll probably never forgive myself ever

I'm not as innocent in all of this
As I wish I was
Hate to admit my heart's all broken up
All because

I believed him
When he said that he loved me
Every time that he touched me
Oh, I didn't have a clue
I believed him
When he said I was crazy
For thinking just maybe
Those rumors were true
He did the lying, the cheating
Goodbye and the leaving
But the one thing that I can't believe is
I believed him
Can't believe I believed him

I've always gone with my gut
Except for this once
How did I end up
Second guessing

Yeah, that last time
Was the last time
That I go outta my mind
Swear that I've learned my lesson

I believed him
When he said that he loved me
Every time that he touched me
Oh, I didn't have a clue
I believed him
When he said I was crazy
For thinking just maybe
Those rumors were true
He did the lying, the cheating
Goodbye and the leaving
But the one thing that I can't believe is
I believed him
Oh, I

Yeah, that last time
Was the last time
That I go outta my mind
Swear that I've learned my lesson
But what I can't get past
Is how it looks looking back
Without a shadow of a doubt
No question

I believed him
Can't believe I believed him

Oh, I believed him
When he said that he loved me
Every time that he touched me
Oh, I didn't have a clue
I believed him
When he said I was crazy
For thinking just maybe
Those rumors were true
He did the lying, the cheating
Goodbye and the leaving
But the one thing that I can't believe is
I believed him
Can't believe I believed him

Can't believe, can't believe I believed him, hmm
