Blondie has some really great advice there to start making new friends outside the JW cult. Get busy doing activities with these friends and you could say" I'm SO busy this weekend.... sorry I just have so much on my plate ! "
The thing is if you come out and are blatantly honest with them- then depending on HOW fanatic your JW family is - you may open a can of worms for yourself greater than the can of worms you already have. Once you become a common conversation piece of elders, fanatic JW family and come into their radar constantly - they will KEEP you the constant source of their conversations and will make it difficult for you to fade away peacefully. I would tell them as little as possible. You do NOT owe them an explanation. Just say " it's personal " - and that YOU are working at it- which is TRUE ! You are working at it in your OWN way, at your OWN pace, and according to your OWN desires- nobody elses.
So this is just an idea , then let them pry no further. JW's are ridiculous and VERY different from people in the real world in that they show NO respect for boundaries or our privacy. Some of the most snoopy, nosy people on the planet in my opinion. But you stand your ground- show authentic family love to them- just stay off JW topics and talk about other interests, movies, music, weather, hobbies you and hubby have- ANYTHING other than JW stuff and I think it will go smoother for you. It's how I've handled my JW family fading into inactivity for almost 10 years now. Good luck ! Peace out, Mr. Flipper
