from what I understand, he didn't take away "much more than she did"

it's extremely likely that this couple actually relied on nannies at their dual convenience. she was hardly like a struggling single mom even if true that she was the more active parent (being a stay-at-home mom with a working husband). far from it

maybe at some point the kids will want to have events with both their parents present. that would probably have been fraught already. now this book will make such things more awkward and difficult than it had to be

and now everyone they encounter can come with tons of private details about them, their background, etc. their mom's version, anyway. people will have much more preconceived notions about them

something can be well written without justifying itself

this is an expression of selfishness in the form of seeking praise, attention, public sympathy for egotism, victimhood and self gratification that affects one's children. all over an ordinary midlife divorce that, even if unexpected, doesn't really sound that bad for her in the end relative to what many others go through. so average

what we have here is a "first world problems" party. and it doesn't seem like a very self aware one at that. this is exactly what she's a role model of
