Personally, I think each ending is realistic in its own way.
Woman: Metaphor that she manages to cut ties with the "Doctor," that he doesn't let her isolate her, and that she manages to move forward in her life by overcoming that trauma. I take this as a reminder that there are survivors who have managed to overcome their "doctors" and move on as free women (Or men).
Wife: I take this as a representation of women who are defined by their circumstances or society, who, in their eyes, truly have no other alternatives and have already grown accustomed to the "doctor's" cage and know the rules to be in his good graces, so despite being unhappy, they stay with him.
Statue: For this, I use it in the most extreme cases (Physical and psychological violence is a common norm in their relationship), where the victim has been completely isolated, and they truly have no means of help, be it friends, family, or even society. Unlike the Wife ending, they don't even have the option to stay out of fear or survival, since they literally have no choice as statues...
(I'd even theorize that this ending represents the murdered victims, although I might be overthinking it.)
My point is not that I think one ending is more "realistic" than another. I simply believe that each one represents, in some way, the fate of abuse victims. Therefore, the Woman ending is my favorite. But we definitely need to be reminded that Wife and Statue are also real things that happens, and we need to have our guard up, whether for our own safety or to help someone who is in a bad situation.
(And the VAs really sold me on the idea that the narration voices were Yuemko's allies, and the representation of her family and close friends<3)
((By the way, in my case, I have a lot of experience with psychological horror games, where the protagonist is in a vulnerable position, and you have to use your intelligence instead of your strength to survive, in this case your emotional intelligence...))
