He says “You have let yourself be deceived”.
That's actually a great conversation point. Start a general conversation about how one can find out if they are deceived or not. Don't drag JWism into that conversation; if anything, try to keep it out.
First try and see if you both can agree on how a person can discover if they are (being) deceived.
Could anyone be deceived? What about you? What about him?
What personality traits and behavior would make people have a higher/lower risk of being deceived?
Would unquestioning trust put someone at risk?
What about limiting one's information intake?
What about declaring some topics as off-limits for doubt, discussion, dissent?
Once you can find some common ground there, you can build on it to see if either of you are deceived. At first you could present it as a way for both of you to find out if you are deceived. Don't try to be right. Don't try to defend you. Try to make him think, even if it's a single hidden 'aha' moment in his brain.
He is the type of person that will never admit he’s wrong. Thinks he’s the smartest man around. And admits he struggles with humility.
Interesting. Just this week I read this: Intellectually humble people tend to possess more knowledge, study finds. People who think they know it all, actually know less. Lol.
He compared me to Eve.
At first I thought that's just lame and sad. But when he brings that up again, don't take it as an insult of trying to blame you for his own failure (which it really appears to be).
What he is also saying is that he loves you more than he loves Jehovah, and he loves living and dying with you more than living forever without you. So thank him for that (sincerly, not sarcastically). Or ask him if that is his motivation. Because that would be really sweet.Additionally if you look at it that way, there is zero need to feel guilty...(Of course it could also be that he doesn't yet know he doesn't actually believe in the JW God and paradise and eternal death).
