The comments here are strange. People have universally decided that the two women are unhappy with their husbands. I got the impression they loved their children, they are happy, and the love they found with each other was added happiness. You are all presuming way too much about the part of their lives you aren't shown.
The same could say about your interpretation though.
That's fine. But why, given that the only thing we see from them is that they are happy, do most people assume that they are dispairingly unhappy and practically human slaves to their husbands? So melodramatic.
It's a good thing one of them didn't have a bruise from bumping into a table or something; everyone would be absolutely certain that the husband came home and beat her to death each night. :P
