<modsnip> Well, here's some information.
Normal women reveal this kind of thing a LOT. And many of them do it on their public (not even private) facebooks! Even more, women actually ask each other pointed questions of this time - and yes, we are normal women who do this.
I am normal, but introverted. Still, with my best friends...OMJeez, are we likely to ask each other questions. And I had a perfectly normal man (who I don't know well at all) call me up and ask if I could procure medical marijuana for his wife.
It would be abnormal for a woman whose doctor had mentioned a treatment (and whose husband opposed that treatment) not to bring it up with sisters, daughters, good friends (we know that Suzanne had at least one good friend - obviously, it's normal to speak to them about such things!)
Seriously, I have women who know me only as a professor email me/tweet me/reach out to me on all kinds of matters that none of us consider "intimate," just, you know, things like depression, cannabis, anti-depressants, domestic violence, birth defects, neurological illnesses, serious illnesses, etc.
Listening only to the opinion of one's husband in a matter like this is abnormal. It's actually a symptom in DSM (Dependent Personality Disorder for one).
It should be really clear that a woman who didn't seek separate, personal advice in such a matter is truly in the orbit of her husband.
We've been using the word "controlling husband," would it help if we simply said "a closed system in which the male member makes decisions typically made by the individuals suffering an illness"? A closed system in which the male member is the decision-maker who from near and far, controls the length of the leash allowed to the other participants.
If the people around Suzanne looked at her as abnormal for trying to form an independent opinion, no wonder she didn't want many friends and carefully confided only in 1-3.
