:I know he is going to go through alot of grief and pain when he does realize the truth about it...its like his whole life has been a lie.
Since you were only a JW for a short period of time, it may be hard for you to understand just how significant that statement above really is. For born-ins like me who had to face up to the fact that our entire youth and early adulthood was literally wasted for a lie, evoked a rage that cannot be described. It takes a while to get over that rage, that anger and settle down to deal with the blame, the grief, the sadness and finally the acceptance of it all.
It is easier for some than others, but it is never easy. Be patient.
With regards to your husband's blind trust in God dealing with organizations and the Watchtower Leaders frequent statements that Jehovah has always dealt with organizations, ask your husband to name one Bible prophet (including Jesus) who was part of an organization that Jehovah approved to run things for Him.
Virtually ALL Bible prophets were individuals being used by God to condemn organizations (like the Israelites) that God disapproved, NOT that God favored.
