Hi darkknight - there are a lot more experienced people than me on this board who can help you with fading advice,. Just wanted to say as a woman and a mum how sorry I am for you and your wife, my sister went through this heartbreak 3 times but finally has 2 lovely children, so don't give up hope (I'll pm with you with the treatment that worked for her, just in case it's relevant). The organisation is terrible at shepherding people through loss and trauma, they only tell people to do more and are always ready to reprove & discipline. It sounds like maybe your wife is feeling this too and a bit of time away from the meetings, maybe a few weekends away here and there might do her good, and get her out of the mind control....
I am sure it won't alarm her if you just say 'do you ever have any doubts....?', if she says 'what no! never!' you know where you are, you can just cover it over quickly and say 'I don't know what's wrong with me, think I'm a bit down' or something like that. But she might say, 'well actually, yes.......'. I like Giordanos suggestion of starting with the child abuse issue, for any one with maternal tendencies this is a crucial aspect for awakening. I mean, 1006 pedophiles on file in Bethel in Australia alone and not ONE reported - that's got to ring alarm bells for any decent human being. Best wishes to you both x
