This always weirded me out...If a JW's spouse dies (and lets assume they were reasonably young) and that widower re-marries, has a big happy family, etc etc...
now imagine resurrection day.....the last thing you remember is this person was the love of your life, your entire universe, your raison d'etre, and SURPRISE! They have moved on without you, and you are left high and dry....can you imagine the psychological nightmare this would be for the "resurrected"???? Would you even WANT to come back to that???
