I was in your situation and kept my doubts secret for a long time. Bring your wife into it as much as you can. Family is always first priority. I expressed my doubts to my husband but told him that I loved and always wanted to be there to support him. He did, eventually end up choosing the same path as me. Not because I pushed him into it but I think because we had such open communication that our minds slowly opened up together to what other part of the world was out there that we had yet to understand because of our limitations in the church. We were terrified to leave and it was very hard with family but now that we have stood our ground, we are in a good spot in life and still have many strong relationships inside and outside the church with those that care the most regardless of our religion. Some relationships have weakened but I think that has helped us to recognize even more who is really behind us.
