What's wrong with the marriage of Nora and Torvald in A Doll's House?

Nora and Torvald have a shallow marriage.  It is based on
possessive love.  Torvald believes Nora is his prize possession. He does not deem her
his equal.  She is his play toy.  He believes he is intellectually superior to Nora.  He
does not have a clue about what she really knows.  He is programmed by society which
keeps the humble little woman at a man's feet, not by his
side.

Nora plays along with Torvald and pretends to be just
as shallow as he is.  She takes on the part he has given her.  She is his little
squirrel or little songbird.  Nora is an intellectual who has to keep her knowledge
undercover.  She truly loves Torvald enough to sacrfice her reputation by secretly
borrowing money for his health issues.  In return, he shouts at her and sends her to her
room. She is his child, not his equal.  Torvald worries about appearances.  He is all
about keeping up with the Jones.  He worries about his reputation and will not
sacrifice, not even for the woman he loves.

Nora on the
other hand is willing to do whatever she must do for the man she loves.  If only Torvald
had appreciated her true love, perhaps they would still be together.  Nora has no
choice. She must leave Torvald to find out more about
herself.

Torvald had it all.  He had a woman who truly
loved him enough to sacrifice her own feelings in order to make him happy. That is why
she played his silly games.  It is too bad that Torvald was blinded by his own ambition.
 Will Nora return to him is the question with which he is left wondering? I would guess
that he has lost her forever.
