Op, I have had a converstatokn around this about my exh.
After I have left, looking back, he wasn't a lovely guy. He was always controlling but always managed to do it while being the good guy.
During the back end of marriage it was clear he believed a few conspiracy theories. He hated that I didn't. Then we started with flat earth theories. Stories of flights that had taken off in one place had to emergency land, but ended up somewhere it should have been impossible to land. His abusive side got worse and worse. He became hugely paranoid.
It escalated, I left. Over the pandemic its gotten to the point my daughter chooses to not have anything to do with him. He sees our son occasionally, but is upsetting him.
I have had ranting texts this week about how he is withdrawing his consent for the kids to have test, because the swobs are dipping in a chemical to give us all brain tumours.
Apparently the governement has decided the best way to kill huge amounts of us, is to give us an illness that costs a fortune for the NHS to treat and takes a long time to kill us.
In March 2020 he was asking people to tell him if they saw a 5g masts, as he knew someone who would put then down and save us from covid. Vaccines have microchips, is a social experiment, and will kill us all. Masks cause lung infections even when used correctly, the governement wants to know everything he is doing and so and so on.
Its now manageable as we don't see him and he doesn't know where we live. But its not got better. He keeps meeting women at meet ups and it appears that they then increases eachothers paranoia, then they break up after a year.. He thinks he is oh so much cleverer than everyone else which is why he can see what we can't.
Its just awful. I have blocked him but the he turns up at my parents telling them the kids are in danger because I have taken them to a doctor. My daughter blocked him and he turned up at her college. We are all trying to manage it so he doesn't kick off too much. He is currently looking to kove to a cabin in some woods so he can be off grid. I hope he actually does that.
My personal opinion its paranoia and arrogance that is fuelling this.
