If your marriage is about to bust then why not go for the throat so to speak. Bring out all the child molestation issues and show him the documents, nothing from an apostate web site but from other sources. then show him sweet little scriptures that he will not be able to deny.
Like John 20:25 where it says nails showing Jesus was killed on a cross not a stake. Or even Rev. Chapter 20 were it does not say anything about a new scrolls being opened. Show him in the Greek interlinear Rev. 5:10, there its doesn't say they will be Kings and that they will be on the earth. Then back up to verse 9 have him read then flip over to Rev.7:9 have him read this and see that it the great crowd that's being talked about not just the 144.
Ask him how the bible is apostate? Or is it really his religion? Ask him what his understanding of the good news of the kingdom is? Then show him 1Corth. chapter 15 and Galatians chapter 1 where it states that Jesus , is the good news, Not a government or anything else the JW's say.....
