Welcome.
What an accomplishment-two years sober. It is something to be proud of. How wonderful that your wife stood by you, and that you have her and two children. You have so much...also you mention a brother that is "out." Sounds like a good support system.
Yes, as the others have said, please be patient with your wife as she must have been patient with you many times. Stand by her decision to stay with the JWs. She has two children that she loves more than life and must fear Armageddon coming sooooooooooon and what could happen to them if they leave. Take it slow.....just take your family to fun places on the weekend. Little by little she may enjoy time away from the KHall.
If you must speak about the WTS, phrase your doubts as a question..."Should we think about saving for college for the kids or do we feel that they shouldn't have the option of an education?"
Hope the best for you!
