This was... Magnificent. All I could think about was how much rage was flowing through me. Especially when you said about Oliver doing drugs, but that's a whole other story. I'm just overall impressed with this story and all the imagery. If you haven't thought about it, I highly suggest turning this into a chaptered story... Or at least have one more chapter explaining everything even more!
I can't even tell you how much this captivated me. And yes, I have totally had those violent thoughts! I'm sorry that your ex cheated on you, but on the bright side it prompted you to write one of my favorite pieces on this site and my favorite one shot! I loved this, it was amazing. Please post more on this site!
