You treated me so unkind, my love for you was blind
I should've know, I should've know, I should've know better, baby
All the signs were there to see, out chasing girls when you're here with me
What am I supposed to do? You treat me like a fool
And you took my heart, left a scar
Don't pretend she's just a friend
Why are you so cruel
Acting like you do to make me
Jealous, jealous, jealous
Jealous, jealous, jealous
Tell me lies to humour me, playing on insecurities
I should've know, I should've know, oh I should've know better, baby
First time that I met you, I told my doubts I was lost for you
What am I supposed to do? You treat me like a fool
And you took my heart, left a scar
Don't pretend she's just a friend
Why are you so cruel
Acting like you do to make me
Jealous, jealous, jealous
Jealous, jealous, jealous
I don't wanna question where you are or who you're with
But you're testing my patience, playing games and running tricks
Is it too much to ask you just to be love
Why are you so cruel acting like you do to make me
Jealous, jealous, jealous
Jealous, jealous, jealous
Oh no, jealous
Oh no, I'm jealous
Oh no, jealous
Oh no, oh, I'm jealous
