Hello and welcome! I'd recommend Steve Hassan's books on Combatting Cult Control to help you to free other loved ones, there's a skill to this, and you can learn it. Based on my experience of losing my kids to the WTBS, I'd have to tell you to run fast and leave it behind them and you before it's tentacles ruin your family. But I do get that sometimes it's not so easy...so...I'd build strong family traditions and be sure to place the unity and love of your family above anything, and I mean anything JW related. Without traditional holidays etc it won't be so easy, cos those things are what cement family memories and bonds.
I can't urge you strongly enough to escape and bring up your kids in freedom though. What about a strategic fade so that you keep some extended family, once of course you've managed to help your other half? Lots of good info and support here to help you.
