Mistake number 1- You married a JW.
Mistake number 2- You should have started educating your husband sooner.
This stuff does not go away unless somebody does their homework exposing the fallacies that have been repetitiously ingrained in his mind for probably most of his life. Sooner or later, it resurfaces. Guaranteed.
Now, Good move number 1- You are here. You will be able to gather all the information you possibly can to expose the JW religion for what it actually is and if your husband pays attention (no guaranties on that sorry to say), then you can start to deprogram his mind.
If you do nothing, you will lose. Because the JW's are doing everything they can, every time they can, to get him back to the meetings and into the full JW routine which to them means he lives.
Ray Franz is the best source out there, as already suggested. But, he may not go for that quite so fast. Most JW's consider Ray to be the chief apostate and right hand man of Satan Himself. So I'd suggest sharing some personal experiences and specific issues with him.
Here is my own story and reasons for leaving not too long ago:

I was a very active Witness and Elder. Let him see that many people are willing to examine the WT Society because of the net. Information is a good thing. Just like buying a house or a car, you want to know whatever you can about its history and track record along with current info before signing on the dotted line. You simply want both of you to honestly examine the Watchtower Society carefully. He should accept this reasonable way to go about this. If he is not willing to examine, then you are in trouble. Which is where mistake number one and two above come back into play.
There are so many JW problems that you can share with him to get him thinking and to take off those blinders. But also be careful that you do not overdo it too fast. If he feels pushed, he may resist. Lead him at his own pace.
By taking the time to get fully involved, as you are here, you can truly help him. Being here is a huge move on your part. Let us know if we can do anything to help.
I wish you all the best!
