Everyone ends up settling down and having babies. It is called a happy ending. I remember having second thoughts when I read her "conversion" to healing and growing things rather than fighting once she accepts Faramir. But then I remembered that this is Tolkien. The problem with oversimplified grids that label something as anti-feminist if women go from fighting to tending is that it ignores in this case the underlying valuation in the whole of this literary universe. Growing and healing and tending is the supreme good. It is not necessarily tied to a simple male/female axis, and I think forcing it into that is a serious mistake in this case.

Faramir is the hero, rather than Boromir, precisely because he belongs to the "party" that Eowyn joins. Aragorn reaches his potential only once war is over and he turns to tending, growing, healing. Orcs fight, elves tend. Men are at their best when they do the latter.
