Hi Normalfulla,
So sorry to hear that you too have been subjected to such inappropriate behaviour.
Simply knowing that this is completely immoral and unethical behaviour helps to put it into perspective, and deal with it. Yes, it hurts to be spoken of in such negative and hurtful ways by people that we once were so close to. However, such behaviour also helps to reinforce the fact that we have escaped from an abusive cult.
At the end of the day, if former "friends" will allow their view of you to be affected by gossip, slander and rumours, then this proves that they are NOT healthy people. You don't need them in your lives!
As @wake me said, we have travelled this road. You are not alone. But believe me, it gets better, as these experiences help us to appreciate the difference between TRUE friends, and mere aquaintances with whom we once shared a common faith.
