rjharris' Scripture-choked response would have me running back to the KH in a weaker moment. Puh-lease!
Reassure hubby that it is very common to have urges to return...esepcially if raised in it. It is not unique to the JWs. Back sliders are common in all groups. But in smaller, more authoritarian groups it can be more intense. A variation on, "Can't live with it/Haven't yet figured how to live without it"
Although, if I can say so, I'd find it very annoying to have a spouse who kept sharing with me their misgivings about their back-sliding status. What does he expect you to say or do - I mean really?
