Splash,.. over 18 I think it is,.. as I have this for my minor kids,...
Your Soulmate is indoctrinated into a cult.
It's very hard to get a person out of a cult.
The only way you will ever find peace is to move on or get her out of the cult.
Read Steven Hassans books on "Combatting Cult Mind Control" and his other books to see what she is going through.
Is she open to looking into her religious beliefs to see if they are in alignment with reality?
If so you might be able to get her to slowly look into what she believes to see if it matches reality.
Again, it is possible to get someone out of a cult but it is VERY difficult to pull off.
