At some point in time you will have contact with Witnesses, whether the new congregation's elders or acquaintances from the old congregation, and they will corner you with questions. You can either lie to them or just figuratively rip the bandage off and be honest.
The only thing that happened like this to my wife and I was a Witness my wife used to work with reached out to her for help on a job. He dropped it off at the house and when the job was completed he picked it up. My wife told me that when he comes to pick it up he will question us as to why we are no longer active and he did. Here's how I responded to him -
"If we are each responsible for developing our own individual relationship with Jehovah I think it would be improper for me to tell you why I am no longer active. I became aware of things through study and research that brought me to this decision. It would not be right for me to try to influence your relationship by sharing everything I learned.
"What I will tell you is this - I cannot associate myself with an organization that intentionally hides the criminal behavior of its members. Hiding child sexual abuse for the perceived idea that it will maintain the integrity of the organization's reputation is not only morally wrong, but it directly violates my sworn oath as a peace officer. Romans 13:1-7 states that I am a servant given by Jehovah and I carry a sword as an avenger to spread wrath against the one practicing what is bad. I cannot support what is directed to me by Jehovah under scripture and the opposite which is directed by man made policy of an organization."
The Witness paused and said that I gave him something to think about. We never heard anything after that.
When leaving the organization there is no "Eat your cake and have it, too" scenario. At some point in time Witnesses will figure out what's going on and act just like you would imagine they would. The important thing is that you fill the void of family and friends with new family and friends.
