I think I have on this once before in the post PTSD. I believe it important to circle back to this point as it is often missed by members of family of future and current cult members.
I was twelve years old when we were courted by Kim’s group. My father was the only one who spoke up when we presented the idea of moving into the cult. Because it was a decision I was in support of I did cover up to some extent the reality of it to my father. All of this is subconscious and as a cult member you are not aware of the guarding.
My grandparents were brought into the fold by my father, and their apathy ended up being perceived as support by my mother. This put the nail in the proverbial coffin for us moving in.
My point is this, do not sit idly by while your relationship with your family member slips away. Life is only so long, and losing them to a cult is a reality and not overstatement. Any kind of intervention would have prevented this. My dad did his best effort with me and leveraged who he could… Unfortunately those he leveraged didn’t step up in the same way.
