If you *do* decide to meet with him/them, I would strongly encourage you to not attack doctrine or admit *ANY* activity that they would consider questionable as they will likely use that information against you and take judicial action. Don't engage them in any topic/subject.
Admit nothing but feeling discouraged by the complete lack of love shown withing the congregation.
If they say 'imperfect' people. Call them on that bs line. If nothing else, members of a loving organization group will reach out to a member when they take ill. Send a card, bring soup, offer a ride home. Something.
Discouragement and depression without elaborating on any specifics seem to be the only acceptable 'excuses' for not attending meetings. Well, not really acceptable, but mildly tolerated.
Admit *nothing* about beliefs or actions or friendships or affiliations or relationships, if you want to avoid the DF or DA label.
Please come back and tell us how the meeting or conversation goes.
-Aude.
