my boyfriend’s family is into premanand maharaj

Idk what to say or do. we’ve been dating from a long time but i never thought it was this down bad until i saw a portrait of the “maharaj” in their house few days back and IT WAS SO BIG. His family is pretty much educated. Yes they’re religious and i like that. they don’t eat non veg, onion or garlic. they visit Vrindavan just to see him like every week. It’s crazy. It’s like they follow whatever he says. he tells me to start listening to him as it would make my life better? i’ve told him i don’t believe in all this and i will never believe in a human but he says his lessons are good even tho i find it all so fake. what should i do cause i’m genuinely scared.
