You and I left the Watch Tower cult under similar circumstances, and I've been shunned by my jw family for 25 years. I overcame the resentment by seeing these people for what they really are; unhealthy association. In reality, both of our families would've rather seen us endangered or dead at the hands of our jw husbands rather than have a free, safe life. It isn't any different than letting us die due to a lack of a blood transfusion.
Personally, I don't care whether their shunning comes from their own evil, cult influence, or a combination of both. The fact remains that they don't have our realistic best interests at heart. If it was anyone else, would you want to associate with delusional people who would rather see you die than disagree with them?
