My ex got radicalized on Stormfront and accused me of "muddying his bloodline".
And yes he did eventually realize that some of that was bullshit, he is not like he was before he got propagandized but not as bad as he was in the thick of it.
White power nonsense. He ended up speaking a whole language I didn't understand. Was absolutely convinced he had some deep understanding of reality that I did not. I think he still holds on to some of it but quitting alcohol helped and getting a job helped, he sort of had to hit bottom to bounce back.
I left when he tried to choke me in bed (woke me up, not sex play), then realized what he was doing and stopped and freaked out.
When we first left my older kids said they wouldn't even go to his funeral if he died. They have since reconciled but certainly are not close - they and I appreciate that he's trying now, but I have to say that when I left and my life got so much better while his got so much worse I did feel a sort of happiness about it. A breakup is never one sided, I did also do and say things I regret, but time kinda proved he was the problem.
I guess everyone has a crazy ex but I honestly did not see that coming, we had over 15 good years before he lost it. And I absolutely blame the right wing fascist conversion machine.
