Wife wants to raise kids in the faith but I'm struggling

This might get some pushback but I need advice. My wife is very dedicated to raising our kids with strong Christian values and I respect that about her. But honestly I've been going through some doubts myself. I keep showing up to church and family devotions because I know it matters to her and to our kids, but I'm not sure what I believe anymore. Don't want to fake it in front of them but also don't want to undermine what my wife is teaching. Anyone been in a similar spot? How did you work through it?
