Pick the right, peaceful, cordial moment and inform your husband that you're not of the same mind religiously speaking and that you'd appreciate if he respected you in that regard.
After that, whenever you get the smallest hint that the JW indoctrination is coming from him, nicely remind him about it again, and again, and again, until he finally gets it.
My husband currently understands that I'm not wholeheartedly in the religion and he leaves me alone for the most part. I've even gone as far as telling him the truth about why I'm still somewhat in, that it's because I need to talk to my family, and that otherwise I'd have left a long time ago. He respects that and really leaves me alone. The only difference is that we truly love each other and have so much personality and other things in common.
The only thing I regret is that he really loves his religion and because of me he won't be able to get as far as he deserves inside it. He's a truly good guy, and good Christian.
