My husband is walking away from Christ and I can’t stop him

I don’t know what to do. My husband constantly watches YouTube videos in history, religion and science and he’s allowing it to feed into his mind. He watches videos on the exposure of Christ and the “truth”.

It sometimes makes me wonder if I’m in the right religion and failing to be more opened to learning or if I just need to dig deeper In the Bible. I feel hopeless at times because he always makes it seem like Christians are sheep and willing to believe everything
