So sad... But on the other hand, have you tried him? You don't know, you just assume that he would shun you when he knows you're not longer a JW... Sometimes people do surprise us with actions we never had expected. Don't cut him off yourself, out of fear of being rejected! Prepare yourself, emotionally, but take your chances... who knows what will happen if you give it a shot???
Or am I being overly naive thinking this way?
Anyhow, here's a virtual hug for you...
