Hi Nancy,
Sorry to hear you are getting such a hard time. How did she come to live with you in the first place?
You do not say what part of the world you are from but instinct tells me that she perhaps comes from a culture pre JW where the daughter in law is expected to have the mother in law live with them and the daughter in law is expected to care for her in her old age.
If this is the case then she will see no good in what you do, couple that with the JW dilemma and she will feel that you have stolen her son and that you are the reason that she will not have ?good standing? in the class system operated by JW?s. Oh yes, the class system is alive and well within the kingdom halls! Points for the class system includes elders in the family, pioneers, special pioneers, and how many kids raised and stayed a JW, etc etc!
I know because I had first hand experience of who I was allowed to associate with even within the same congregation. My parents did not want me mixing with fellow JW?s who did not come from very spiritual families!
All I can say is try to get out of there as soon as you can.
Good luck,
Scots lass
