I wish I had listened to the nagging doubts much earlier in life. I wish I had made a break when I was young and single. The longer you're in, and then married, and then kids, the harder it is to break free from it. I think it's even harder for an adult child to leave the organization, when their aged parents had grown accostumed to them always being there in faith. Leaving as a young person gives a parent time to cope and eventually accept their child's life as it is instead of as what the parent wanted.
I see that two posters are going through hard times.. bottleofwater and BrotherDan are both at a crossroads where remaining in the orgnization is no longer viable.
The difference is that bottleofwater is young and single. While what he's facing is hard, he has no baggage. No wife/significant other, no kids, no real responsibilities. He'll struggle early on, but by the time he's in his mid-20s this will be in his history and he'll still have his life in front of him...free of the cult. In time his dad may come around and accept his son for who he is instead of shunning him for who he isn't.
BrotherDan is in bad place as well. He's married with kids. He is the spiritual head of this JW family. His relationship with his wife is precarious, at best. He has children, who will be affected. Dan's decision to leave the organization behind just doesn't disappoint a parent, it could possibly end his marraige and cause children some emotional trauma. I don't know about parents, but if either one have JW parents, then it's even tougher as they tend to stick their nose as well.
Even though I wish I had escaped earlier in life, I don't regret my life in the JWs. I did meet my wife that way. I did know some good people, made some friends over the years (still connected a few now even). Also, in a weird way, those years ended up being an education. It is enlightening to a degree to have been a JW and escaped. It gives you a different perspective on a lot of things.
