First cut ain't the deepest

I'm a slow healer,        
So if you're going to cut, cut deep,          
Use a knife,          
Take the pound of flesh,          
Stop my heart quickly,          
Dont twist slowly and take years of my life.          
         
Or speak,          
Allow the promise of truth we applied come through,          
Dont use lies and fuck another man too,      
 Or pretend I don't know what you're up to,          
Taking me of all men for a fool,          
And then pretend it is me not you,          
Retort and add wealth to my mental health!!!! Please.    
Don't raid my mental fridge and leave empty shelves,          
Devour the contents and leave me picking the bones,        
So I need a professional to clean where you ransacked and ruined.          
         
All this as I sent a message pissed,          
All this in a blackout I don't remember after we fought but I apologised,          
We kissed,          
All this for one mistake you had an affair,          
Keeping it going but saying yes to being my wife as you knew I worshipped,        
   
All this,          
For that.          
         
And he had a girl too,          
Did you feel power of illicitly making love?          
I wonder if it was a him thing or if it could have been anyone,          
And I know he is contrite,          
He didn't know me but we met one night,          
In a bar and he bragged about an affair,
Telling anyone who was there,         
We had both had a lot of booze,        
When I was listening to him loving the fact he was fucking the two of you.          
         
I guess this is cathartic,        
As what you did was too much,          
Enough was enough,          
Next time when you hurt a man,          
Strike hard and fast,          
Don't use small cuts.
