He probably is a wonderful human being. Unfortunately this wonderful human being has been infected by the cult of Jehovah's Witnesses. He will be emotionally damaged and immature in many ways. He can be cured but not by pandering to his beliefs and his wishes.
It will be down to him (and him alone) to chose to leave the JWs and move on without them. It is very unlikely you will be able to do anything directly because he will have been indoctrinated his whole life to see all such attempts at help as Satanic manipulation to lead him away from 'the truth'.
I understand that he is probably afraid of losing all his family and friends but that is the price of leaving the JWs.
1 - If you want to join this cult then be prepared to cut off all ties with your current friends and, to an extent, your family. You will lose freedom of expression and be expected to fulfil a certain role in your husbands life (yes that reads correctly: you play a role in your husbands life).
2 - If you want to leave it all behind then dump him. Tell him you want nothing to do with such a damaging, unnatural cult!
3 - If you want to stay with him on your terms tell him you will be honest with his family about your current relationship (i.e. explaining about your normal healthy relationship) and see where that goes...
If you dump him hard he may just go back to the cult and find condolence in the belief that you were just another worldly woman sent to lead him astray.
If you dump him with love and explain why you want no part of a cult (don't mince your words) he will probably run back to the cult and believe you were just another worldly woman sent to lead him astray but he will also have time to dwell on you words and just maybe sort his head out enough to eventually leave the JWs.
