What are some similarities between Nora in A Doll's House, and the narrator in "The Yellow Wallpaper?"

I think that there can be a couple of similarities between
both female protagonists.  This would be the first one in that both of them are victims
to a social setting that does not validate the rights and narratives of women.  This
setting impacts them tremendously, for their experiences are contrary to the socially
constricting vision of what it means to be a woman.  The narrator is convinced that her
condition is more than "just nerves," while Nora really wishes to be treated as an equal
partner and not as an ornament.  Another similarity would be that this social definition
creates partnerships with husbands that are not entirely effective.  Torvald is sad in
how limited he is from an emotional point of view.  He is simply unable to recognize
that his wife is in need of validation.  When she leaves him, he is almost pathetic in
how he recognizes too late that his wife has crossed a frontier from which she cannot be
emotionally reclaimed.  The narrator's husband simply does not understand that his wife
might be enduring something larger than a dismissive need of "bed rest."  When he sees
her at the end in a horrifying dance of ripping down the wallpaper, his uselessness is
evident when he collapses and she dances over his body.  In the end, both women
experience what it is to have a useless or emotionally ineffective husband.  Finally,
the writers of each narrative end it with the women protagonists going out on their
own.  Simply put, the only way that these women will find validation will be in existing
away from their husbands and their domestic realms.  Nora leaves and the narrator
dances.  Both of them cut themselves off from the setting that cripples them and that
seeks to silence their voices.  This might be a statement both works are making about
what women must do in order to find and, in some cases, reclaim their
voices.
