I can somewhat understand CR not knowing where LV was moving, but still seems odd.
He may have learned not to ask questions about touchy financial issues (especially if the financial issues were/are shady), she seemed to move often and if moving involved legal/financial issues, she may have shut him down or blown him off.
If she moved often enough it may have just been “normal” for him to not ask questions. Also there are certain personality types (possibly LV) when questioned can feel attacked and will use emotional manipulation and make someone feel, at best, stupid for even asking.
My guess is that CR learned to keep distance and not question LV financial/legal decisions, including moving.
She comes across as mean and vindictive if you get on her bad side - a control tactic that works with many children and some adults.
I’m guessing the children witnessed this. -MMO
