As a non jw I just have to say if my jw spent the night with someone it sure would be divorce court (if he lived that long, just kidding). On the other hand, the elders told my jw that he would be justified to separate from me & kids because I was an 'opposer'. That would be putting it mildly, I was an an outright lunatic about the whole damn mess and 'apostate' clearly did not cover my feelings, beliefs or intentions towards jw's as a whole.
In the end so to speak, there is enough of his authentic self and our much longer love than than the jw cult can take away. I imagine someday when we are both losing our marbles he will still remember me to some degree and can only hope he will forget jw's altogether like some stories I hear about here and other ex jw boards.
I remember some story of an older person who got dementia or Alzheimer's and forgot they were ever a jw and started going to the church service (mainstream non jw) at the nursing home and the child of said person wanted to know if they should be disfellowshiped for doing so. Can you imagine?! wanting your mom to be df-d because she lost her marbles and reverted back to her pre jw days in old age? Luckily the elders decided nothing should be done.
