... I'm so sorry about it... really sad. The dark and sad side of religions....
On another hand, it also reminds me my own story, even if the circumstances are a bit different ... my partner's mother also
really badly reacted when we announced her I was pregnant (of her first grandchild !). Like "no... impossible. Not
now. Not
me."... She reacted so selfishly... saying stuff, like she was not ready to be a grand mother, that it was not "logical" because my partner wasn't her oldest son... that it wasn't the right moment, because (...) well. She was so... angry ! My partner cried as well, he was shocked, and disappointed... I took my eldest owlet with me (only 3 years old ; he should have wondered what happened... and was about to leave their house, when she grabbed my sleeve to hold me back "ho no, you won't leave !"... ô__ô .... And then I just...yelled at her... i hadn't been that angry for a decade. I thought I could have hit her if she hadn't let me go.... Awesome family memories... !! Now she is totally fine with it and loves her grand daughter, but something is spoiled forever in her relationship with my partner and her... and since then, between my partner and me (he lost his self confidence, and was really depressed for 1,5 year at least. Things will never be the same now...
The importance of "first reactions"... she tried so hard to make up for it afterward... but it was too late.... :-\
I totally sympathize.... I wish things got better for your wife after that, but I doubt... ?
