That’s good then!

I don’t know if he has any hobbies besides getting angry at the news, but it’d help and give you two something to talk about that isn’t upsetting. I know you mentioned in another comment that he sees frivolity as a waste of potential, but maybe you could emphasize that he’s worked hard his whole life, and fun in retirement is supposed to be the reward for that?

What does he do for work? Maybe there’s a hobby that hits his dopamine the same way?

but lately he is getting stuck on topics and gets very very repetitive.

I used to do elder care, and this in particular could be an early sign of dementia.

My parents were involved in a cult, and I never would have made it out if I didn’t have normies on the internet telling me that being in a mass marriage ceremony to Jesus at 17 was fucked up.
