I'm glad she's pursuing a spiritual release. That would give her more finality in the end of that relationship that aligns with their beliefs.
That said, I really do think they give the legal marriage more credit than it deserves. Being legally married to R and living in a community property state didn't stop K from cutting R off from even the possibility of owning the two CP properties her name isn't on. He even cut her off from the possibility of claiming Christine’s house before he took his name off of that.
But I also wonder if these people are reading the contracts they're putting their signatures on. In Christine’s book, she made inaccurate claims about ownership and the timing of K removing his name from her house that conflict with the contracts and the county parcel site.
Frankly, if plural marriage was legal, that would give these men more power and control, as well as more incentive to keep the women as ignorant of their rights as possible.
