Sorry you're going through this, but you need to know the reality of the situation: You're in a cult.
Forgiveness from Jehovah is not relevant to the elders. This organization is about one thing and one thing only: control.
Your spirituality is a private matter. You are absolutely right when you say that there a facts about your life that are "none of [the elders] business." But as long as you remain in this religion and allow them to exercise authority over you, they will continue to try to control you and overstep appropriate boundaries.
It might be hard for you to do at this point, but this experience might have prepared you to take the next step in your spiritual growth and personal freedom. Leave this religion. It's a cult!
