Welcome to the site.
Your story was very interesting to read. Thank you for sharing it with us.
As many have already mentioned, your JW family will try to convince you to return. Remember that, and always try to understand their side. It will be much easier that way. As far as they are concerned, they have the indisputable truth, which you have left. Also, remember that their indisputable truth is utterly dependent on what the Governing Body says. Don't even try to reason with them from the Scriptures as they will always, whenever proven wrong, rely on the interpretation given to them by the Governing Body. (It's just my friendly advice in regards to wasting time.)
I do hope, however, that your family will respect your decision. Good luck.
