SW - I hear what you're saying. I use a similar strategy when people ask me about the borg because I still attend to keep family happy. I even turn in fake FS reports.
Their specific purpose will be to try to find out why you are inactive and not going to meetings. It's fine to say you believe everything but you'll need to have a believable reason why you're not going. You were stumbled, depressed, discouraged, something.
I'm sure he hasn't said anything about your doubts which is good. The problem is because your husband is an elder, it's attracting more attention.
You are right, they can't DF you if you don't give them anything. Just make sure you yes them and you'll be fine.
I've refused numerous shepherding calls because I"m not confident I won't get angry and say things that will cause me problems.
