My girlfriend slept with a guy at a university camp and then got angry at him and cut one of his dreds off. She told me about it as soon as she got back. I’d met the guy and thought him a douchy child, but i mostly felt sorry for him. I was a bit disappointed in her choice but i wasn’t hurt or anything. A few weeks later i drunkenly kinda went to bed with a housemate who i then realised i’d been crushing on, and my girlfriend and i admitted there wasn’t really anything there and broke up. When i first told her that me and elizabeth made out she was like, “Aww, go you!”
That was a real “no harm no foul” situation. Years later i went on a 3 month holiday and never came back. Everyone but me and my then girlfriend realised i was just moving overseas. She was way more into the relationship and I was too cowardly to break up. We carried on long distance until i found someone else. I broke up with her before anything happened, but she was hurt and it felt like cheating in a way that the more technical cheating above had not.
His behaviour is televised daily and has been for over a decade. Most of the world has seen his mental decline. It’s obvious in his speech and actions.
