Watched you pack your bag
With your t-shirts from my drawer
I guess my place ain't
Where you keep your spare clothes anymore
And when you stepped onto that plane
To go sleep by her side
I had to come to terms with how
The whole was a lie

And then I've realized

The day you broke my heart was the best day of my life
No I couldn't see it at the time
I should send you flowers showing my gratitude
'Cause I wouldn't be happy if it wasn't for you
Breaking my heart was the best day of my life
It would've sucked so bad if you made me your wife
I thought my life was over, it was only the start
Yeah the best day ever was the day you broke my heart

Now I don't have to apologize
For feeling what I'm feeling inside
Don't have to feed your ego all of the time
And now I kiss really hot guys
Oh, I feel sick when I imagine
Where I'd be if it hadn't happened
'Cause it all came together
When you tore me apart

Yeah the day you broke my heart was the best day of my life
No I couldn't see it at the time
I should send you flowers showing my gratitude
'Cause I wouldn't be happy if it wasn't for you
Breaking my heart was the best day of my life
It would've sucked so bad if you made me your wife
I thought my life was over, it was only the start
(I thought it was over)
Yeah the best day ever was the day you broke my heart

Ooh

Yeah the day you broke my heart was the best, woo, day of my life
No I couldn't see it at the time
I should send you flowers showing my gratitude
'Cause I wouldn't be happy if it wasn't for you
Breaking my heart was the best day of my life
It would've sucked so bad if you made me your wife
I thought my life was over, it was only the start
Yeah the best day ever was the day you broke my heart
