I do earnestly hope that he can eventually be made to see the JW organization for what it really is – a deceptive, manipulative, high-control cult – and that you and he can renew your relationship. That would certainly be the best outcome for you both. (Don’t forget http://www.jwfacts.com/!)
But if he can’t somehow ever be made to wake up and come around back to sanity but you still want to try having a significant relationship with him, then, well, all I can say is, Fasten your seatbelts. It’s quite a rough ride indeed when the one you love gets commandeered (high-jacked!) by the likes of the Watch Tower!
