What do you think about the situation?
It happens all the time. There are far fewer men than women in the organization, which is a problem because they do not approve of marriage outside the organization, and do not allow sex outside of marriage, which creates this situation of dating on the down low.
Do you know of cases where people got kicked out of their home because of disassociation?
Yes, it happens all the time.
What would you do in my situation or in hers?
She should research the history of the religion and find out how much of it is based on lies and half truths, that would free her to date whoever she wants. I dont expect that will happen because this is a cult and they use manipulation and mind control to convince people they are the only true religion and if they leave they will die at Armageddon, which is happening any day now. Its almost impossible to counteract this. For example, she believes anyone who leaves the organization and speaks out against it (like me) is a "mentally diseased apostate". She will believe anything I or anyone here says is from Satan.
I would advise you to forget her and find someone without all the baggage.
