Best information here: NEVER meet with them or do anything else that "validates" their position of power in the bOrg. Remember....these are not really servants of God, they are just guys who happen to go to church with your hubby. Think about it. Don't play THEIR game -- make them play YOURS.
Can't possibly imagine what in h*ll your husband was thinking in ratting you out...what did he hope to gain? Sorry, but he's just plain weird for doing that. Sounds like he's more interested in getting sympathy from the eldumbs than in getting love and affection from his wife. Not sure how you feel about him but his actions say Idiot.
Protect your children at all costs and never, ever let them be involved in this eldumb craziness -- including this trumped-up drama nonsense about celebrating holidays. Play the lawyer card and play it fast, even if you don't have one. The threat should be enough to send them running away.
Congratulations on living life with your kids! Keep up the great parenting job.
