I only stay so that I don't lose my family to shunning. I'm probably a wuss for doing so, but hey, it's my decision.
Not at all. Some people are willing to accept those consequences, some aren't.
The problem begins when the family begins to suspect that you're weak or apostate. Then, every time the talk to you or you see them it will be a double dose of subtle (sometimes not so subtle) WT infomercial. They'll casually talk about the latest magazines, or the great talk they heard, or all the great new people at the hall. You either learn to bear it or you blow up one day and tell the truth.
The important thing is that you're out and don't believe, and thus the destructive cult has no control over your life any longer....hang in there.
