I've had something similar happen to me. My brother left the church and ever since the only thing he wants to do is talk to me (and my kids) about how I'm wrong to stay in the church. I don't recall us ever having a religious conversations prior to his exit so it's been a bit jarring. I get that he possibly feels he's got to share his point of view, but at some time (especially after he's made his point) he's got to let me live under my own understanding. And anyways I'd just like my brother back, he was fun.
