I, at one or two points in the past several years, considered doing just that. Mostly, for my grandmother's sake. She's gone now, so that isn't an issue, but believe me right after her death my family tried a huge campaign to use that to get me to come back. "It was grandma's dearest wish that you make things right with Jehovah." What kind of manipulative trash is THAT?!
I couldn't, though. I realized that my family would still treat my husband as an outsider, and the worst part is that it would be like giving my full endorsement for them to brainwash my child. I couldn't let my silence be agreement with the screwy things that they teach.
It's a very individual decision, of course. You have to do what you feel is best of course. If there are no kids to consider I think it's an easier choice to make...just be sure that you know that your family will really accept you if you go back and then fade. I always had the feeling that if I went back, I'd have to pioneer or the family wouldn't believe I was sincere and would continue treating me like crud.
