If you really want to be reinstated Sue it will happen - you may need to be patient.
When I was pioneering I studied with a young lad.
He married an elders daughter and became an elder himself in his thirties.
After about ten years of marriage he and his wife confessed to premarital sex just once before they got married.
He was asked to step down as an elder and they received a private reproof.
A few short years later he was made an elder again.
A few years after that he was made the presiding overseer/coordinator of the elder body - he still is many years later.
So there is definitely a way back if you want it - I just wouldn't hold much hope for confidentiality as the guy I studied with would surely die if he realised EVERYBODY knows all his private business....
