Pushed into the Moor

I am a dealer of broken hearts,.  
I have realized my own viscosity is the friction that causes a fire,.  
That will rip the ones I love apart,.  
I am a serial killer for hire,.  
   
A devastating force that cracks the mind asunder,.  
A billion pieces for us to burn into oblivion,.  
Like midnight stars that reveal the galaxy's wonder,.  
She is the one I struggled with; the processes are Darwinian,.    
   
I am the one that is weak,.  
I wanted more than she could give through her broken door,.  
I will never be able to peacefully sleep,.  
Until I forgive myself for pushing her into the darkened moor,.,.,.,
