Shell,
Hugs from Missouri.
The WT holds those we love hostage. They do this on purpose to control us. Part of breaking free from this grip of spiritual tyrany is loss....of one kind or another. You and your nephew are paying a high cost for freedom, now.
However, time is on your side and you have "broken trail" for your nephew to follow. When he fully understands the reality of all of this, there will be a backlash against the ones that promoted this emotional atrocity.
So, all you can do, now, is feel the pain and keep the hope.
With you in all this,
V
