The chapter in the book Little Women/Good Wives, and the scene in the movies of Jo's proposal and married life are So Important. They show the heroine living a happy and unconventional lifestyle: It says that this life she leads with work, marriage, and very little money is a good, wholesome life. That is so important.
But - I think an overlooked chapter in the books (not depicted in the films that I have seen) is the one in which Meg tries to cook and preserve currant jam. She has a miserable day, turned even worse when her husband John brings home a friend for dinner. For once, Meg snaps at him and he snaps back when provoked.
Eventually, Meg takes some good advhice from Marmee, and she brings peace. The chapter ends with a line about married life foe these two not being perfect - it will always have its difficulties, but peace has been preserved and quarrels will be managed.
In another chapter, after Meg has had twins, she understandable becomes so wrapped up in them that she neglects both herself and her husband. Neither the book nor I are saying that one partner should be a servant to the other. But in marriage, we have promised something of ourselves to them*. Meg has isolated herself from the world and grown irritable while she rarely sees John who spends time at his friend's house instead of being nagged at home.
Again, Meg takes initiative and fixes it. This is a bit of a pattern that we see the world over today, in which women usually take the emotional burden in the home. I have no comment to make on that, it's not the point of this post.
The point is: The book has made a few excellent points through everyday, domestic scenes about marriage which are not (or only rarely) shown on film. The glamour, unpredictability and excitement of Jo's publishing, marriage to the Professor, work and, from a plot-based POV, the fact that she is the main character, mean that her storyline is in the spotlight. I love her storyline. But I also think that Meg's has something important to teach us: If you choose the more traditional path, your life is just as full of adventure and growth, difficulties, pain and pleasures.
