We also left when our kids were teens. I don't think they really felt like a part of the congregation. You see, my husband was not an MS or elder. Like you, he never had the urge to reach out. I wonder why! (sarcasm) This has a large impact on how kids are treated in the congregation. No uber Daddy, no invites!
Our kids are fine. We talk to them about things . We are very open and honest with both of them. Kids are not stupid, they know more than we think. We never encouraged them to get baptized. I wonder why! (sarcasm again).
Be honest and candid with your kids. They can see the cracks, just as well as we can. Our children have found more genuine, caring and kind friends in the "world." I truly believe if our home was destroyed this evening our friends and neighbors would drop everything to help. People are typically kinds by nature. We've just been brainwashed all of our lives that every non JW is sporting a pitch fork and horns. NOT TRUE!
