You asked how he would be if you were sick and needed him. Ask him how he would react if you were in an accident and needed a blood transfusion to save your life? Or barring that, could you watch the man you love so much die because he wouldn't take blood? That's right, they are forbidden to take blood.
By the way, this whole I don't want to cause trouble/I can't stand up for myself in big things if someone treats me nice in small ones is how people end up in cults. Yeah, that JW sends up red flags but oh, they're so nice. Yes they are. Manipulative sociopaths often are too. That's how they get their victims. They're nice when they want something, but when you don't want something that they want for you it doesn't go well.
I think we're wasting our time. You have this guy built up in your head. He's a man of works from a works based cult where it's all about appearances but very hollow inside. You are enamored with him paying for meals and doing the works outwardly, but how much does he connect deeply. He doesn't respect your wishes to the point that you'd have to ghost him. Do you realize that's how many have to leave the cult? To ghost them and start a new life elsewhere? They don't let up. He isn't letting up. What are you will to let happen?
