The elders have no power over you anymore, so there's no need to meet with them. Please also make it clear that they will not meet with your children, and that if they attempt to do so, you will use it in court over custody issues. Probably the reason they asked about your dad is because the elders view your husband and your father as having control over you. It seems to me that they're hoping your dad will straighten you out, so all they have to do is listen to you grovel for their forgiveness....assholes!
There is no negotiating with these jerks. I think they're just trying to lure you to a jc, so they can df you. Your case isn't unique at all.
