Yes. I did the very same thing. I faded out from going to meetings, then I picked up and moved across the country. I'm finding it's much easier to be away from all the JW's and JW family I knew. I gave no forwarding address for my publisher cards, I gave no phone number to the elders (and asked that my family keep my number private...they have always respected this when I requested it, and will always call and ask if they can give so-and-so my number before taking it upon themselves to do so). I also live in a community where soliciting is not allowed. So I haven't heard from any JW's except my parents, and my ex and his wife for a good while now.
Like your wife, I don't really make an effort to call my parents often. What's the point? Usually it's a few words about how their health is, how my job is, then they start talking about the meetings and service, I talk about my new friends and my boyfriend, and they shut down and get all quiet. I can't even share the joyous parts of my life with them because they don't approve of it. So why am I going to keep a dying relationship alive? It sounds cruel, but for my own sanity, I need to keep them at a distance. I have other non-JW family that I keep in touch with and we've talked about arranging visits to see each other.
To me, the benefits outweighed the drawbacks. Yes, I'm in a new state, a place where I knew no one except one person. I had to get a new job. I had to learn my way around. I had to make new friends. But...I'm FREE. I don't have to worry that the knock on my door will be an elder trying to sit me down for a judicial committee. I'm not afraid to be myself and be strong and outspoken for fear that I'm being seen as unsubmissive. I have no fear of celebrating holidays with the man I love, putting up Christmas lights and a tree, playing any kind of music I want, watching and having whatever I want in my OWN HOME without fear that some JW will walk in and report me to the elders.
My life is beautiful. And every day I'm understanding more and more just how abused, sheltered, and controlled I was. Moving, hitting the reset button on my life...it was all worth it...for FREEDOM.
