Agreed that the pregnancy is a big issue. My IC is of course not willing to speculate too much on W's psychological issues without having direct info, but also suspects that W having essentially a neglectful mother during her childhood leading to doubts of her own competency as a new mother compounded with the miscarriage really took a toll on her.
I told W during our last (meaning the most recent, and hopefully also the last pre-DB) that I can understand being afraid of the pregnancy, being afraid of dying. Obviously I don't agree with that being a trigger to leave the M - we can work through this, make different choices and decisions without giving it all up - but I can understand the situation and the motivation to some extent. But tossing in OM, that I cannot understand.
Thanks for the rec - I'll look into the book. And thanks for sharing your thoughts.
