Fade more quickly to minimum first.
Why do two hours a week for goodness sake?
Why attend all the meetings?
I only attend for peace with close family. We have a don't ask don't tell stand off sort of agreement. I show my face at ministry once a month and report 2 to 4 hours. If elders ask to shepherd me or go propaganda preaching I politely but firmly refuse. If they pressed (they leave me to myself now) harder I politely and firmly tell them I'm content where I am and do not wish to join them in the ministry.
When they asked why I would say I have private and personal concerns which I am not prepared to share with anyone except Jehovah (yeah right, like he exists or cares).
If they press further I say we all have private things between ourselves and our creator so please leave me alone.
IF YOU WANT TO FADE you must shut up and be firm about it. Smile, laugh, put on a brave face but do not say anything they can use against you.
Best wishes.
