the first time i went to church was for an apostolic girl. i wasnt in class as i had already finished school. but she was a coworker. other than that little difference i lived the story you described.
it started out being a means to get closer to her but to do that means knowing what she knows in the way she knows it.
the apostolic religion believes in chanting and speaking in tongues. they start and end each service with loud music and shouting and overly emotional outbursts. i couldnt go to one service without half of the congregation in tears.
it got to the point where i thought something is wrong with me because i couldnt show that level of emotion to god.
the thing is that in high control groups and cults the doctrine is designed to corrupt. studying the way she studies will make you feel the way about the cult doctrine the way she feels but if you dont believe it you will be at war with yourself.
i became a well versed agnostic because i couldnt believe like her.
and you will eventually find out she is a horrible person because of the group and you will never get the attention from her or the privacy you hope for because her time is designed to be organization property.
she wont be worth it and you will feel like your identity needs to be questioned from the toes to the scalp.
