Devout cousin

3 of my cousins are devout J. Witness and the older one I have recently started talking regularly after losing touch for some time. It’s not easy carrying on a conversation because she turns it into a religious lecture. She told me my other cousin has an online service, I tuned in just to be a supporter but didn’t listen to it. They know how I feel about religion because we’ve had challenging conversations about it. But again, she told to tune in again, if I got time. I don’t want to be rude but I’m at the point where I can’t handle it anymore. I want a relationship with them on neutral perspective. I don’t know how to tactfully reject her beliefs without affecting our relationship (?!)
