I’ve experienced this personally and seen it many, many times.
But never so frequently than in this day and age.
The “controller” will do everything in their power to isolate you from all that could be good and rich and fulfilling in your life.
Today this is done “virtually.”
Said “controller” will BAN, Insult, Deride, Ridicule, OUTRIGHT Lie About, Defame, Verbally Pistol-Whip, Bully, Interrogate, Dismiss and become generally Obnoxious and Disgusting to ALL who DARE to enter your shared space. To ALL whom “they” deem a threat to “their” perceived CONTROL.
It’s called Controlled & Sustained Isolation and Deprivation.
Sound familiar?
