yup. My most recent ex was being especially cruel, and he was saying that he’s tired of cleaning up my mistakes from my previous relationship. I told him that I already paid for those mistakes, and things that happened before I knew he existed were none of his business… and he said they were his problems now because I was careless then, and that I owed him several apologizes for X, Y, and Z that happened before I knew him. I went nuts and started pounding on his back… mostly to avoid hitting him in the face. It’s the only time in my life I’ve ever gotten even remotely violent during a fight… but even now I’d say he deserved it.
