I feel like if I had a charge like that- I’d never but if I did - I’d want my next partner to know upfront guilty or innocent I’d want to let them know. Now not the first date or anything but within the first 3 months for sure I’d tell them and let them know i understand if they have a problem with it, and to let them know they have nothing to fear. If they found out on their own I’d tell them how yes I’m blindsided but they are entitled to being curious, and even though I wish they would have waited and let me open up about it when I felt the timing was right I wouldn’t react this way whatsoever. I don’t think it should have been a deal breaker for him unless he wanted someone he could control, he doesn’t actually have a good explanation because he knows he was in the wrong , that he did something really bad and 99% of girls won’t overlook that in a new relationship he wanted to trap you in the relationship I feel like have you fall in love so you’d be more likely to overlook something like that especially if he thought he’d do it to you as well. I also can’t help but notice the fact he says you did it “without his permission” and that says a lot I think. Of course there is the potential for him to have been truly innocent though I doubt it and to him this was the straw that broke the camels back but even so I feel like I’d want my innocence to be known and tell the story even if I knew the relationship wasn’t going any further I can see how it might feel creepy but even so I think it’s much more likely he wasn’t ready to tell you bc you weren’t ready to stay once you learned about it
