Welcome to both first time posters. You are correct that you will find empathy and support here. The folks here are at various stages of leaving and coming to grips with the fallout that results from leaving the cult. I suggest you read the posts and take some time to figure out what works best for you in your situation since everyone here is coming from a unique set of circumstances. What works for you may be something entirely different or a combination of what others have done.
It is normal to feel confused and betrayed - a feeling that can take quite a while to resolve. As for your wife JWinprotest, my heart goes out to her. She has a double whammy there with a best friend and mom rolled into one. Give her some time to sort things out. Hopefully, she will come to realize the toll this is taking on your little ones and will want to spare them the harm of growing up in an organization based on lies.
Good luck to both of you and keep reading.
