WIBTAH if I asked my roommate to stop bringing up church with me.

I try to be a unjudgy person on other people’s beliefs, but my roommate likes to ask me to go to church with him, or will randomly tell me about some gospel. I’m wondering if it’s wrong of me to ask him to stop doing it? I still want to respect his choice to believe and express it. I just don’t want him to bother me about it. But he also has a complex where he believes that what he thinks is what’s true. So idk. He knows I don’t believe in it anymore and does it anyway. I’d also like everyone who answers to respect my lack of belief and just tell me if I’d be in the wrong.
