Had an update from my son today. It seems that some JWs did come round this morning to 'comfort' her but she was too upset to see them - she told Ben to tell them she was too ill and went upstairs in tears. I believe she is ill, depressed and has been for some time. She still cannot accept that Ben is Gay or that all her children are leaving 'the truth'.
Ben told me that Chloe has back-peddeled somewhat and has made concessions for her mum's sake - I don't know what that means, possibly more studying etc. I did warn her to expect heavy-duty guilt pressure from 'mature ones' in the congregation. It seems so wrong that Chloe is forced to put up with such crap at the age of 15. Of course, being a JW, my Ex has NO friends outside, and I suspect that the counselling provided by her employer will be little help because they just won't concur with the Society's way of dealing with all problems (more service, study, meeting attendance).
I've suspected for many years that my Ex wasn't firing on all cylinders but I really don't think she would harm them physically, and my children are used to her "You know what Mum's like" is a common expression from them. They are very mature for their age and I am confident they can handle things. Ben is 19 now and parents aren't important anymore except as a source of funds!
Anyway, we'll see how it develops.
