The new recruits are courted and they fall in love. The recruiters try to get a commitment within the first 6 months. The marriage is the baptism and the honeymoon lasts from two to five years. The divorce is the walking away or the disfellowshipping. Just like any other marriage, many do not leave . . .
Every case is different.
The decision whether or not to try to intervene is a true dilemma. Many who are studying go to the internet to check on the Society themselves and many of those, without any help from relatives, do stop the studies. For those who do join the group, my personal feeling is that children should never be allowed to be under the power of a believing Jehovah's Witness, ever. There is too much evidence that supports the fact that children's lives are being offered as sacrifices in support of the Corporation sponsored blood medical non-treatment guidelines enforced by the local individual Witnesses.
