One Mistake

It's all downhill from here
It's almost over
A life that I thought I changed
Was just a lie and a smile
And nothing more
I thought I could change things
I thought I could kiss your mistake better
And it would all go away
But it's still happening
You promised me that this was the end
And that it was all going to be okay
But how many times did you practice those lines?
It's sad how I believed you
Every single time
I don't know if it's your fault
Or if you're sorry
But all I know is that this is
One mistake that I can't fix
One mistake that already ruined
Not only yours
But my life.
