You say I'm the one
Your one and only
You say you only have eyes for me
That you don't look at other girls
You say I mean everything to you
That you don't want anyone else

BUT then why
Why do I feel my heart clenching
Every time you talk to her
Every time I see you two laugh together
Every time you talk about her
Every time I know you two are together
That's when a little pieces of my heart breaks
Even though you told me I was the one and only
That I should trust you
Believe what you say
Cause we love each other
So you won't walk away
But to be honest I'm afraid
Afraid that you will find something better
Someone better
And I will be left with a heart that's broken
With a love so strong it will tear me a part
And with tears streaming down my face
While you will look at her and smile

So yeah, I don't quite believe the one and only thing
But that just cause I'm afraid
Afraid and jealous
Afraid of losing the best thing I have ever had
My first love and the only one I ever want
I'm afraid of losing you
My one and only
