Simon you sound like my husband - she was 18 and knew what she was doing! I tried to tell him that's only a baby! I was trying to defend the poor girl having been shoved aside by the cult but under age, naive, girls - no excuse.
She was either enticed with the money, clothes, prominent clientele, Barbie doll delusions, or knew what was going on and didn't care. It's not like she was from a deprived home - educated father/good income.
