There should be a point to the dialogue. People talk all the time, you don't recount everything they say in your novel, only the stuff which moves the story on, and then it is stripped back to show only the essential stuff.
So dialogue about what's for supper, whether to put out the good knives, if the dishwasher had been unloaded, etc should be skipped, and you go straight to the bit where the wife accuses the husband of cheating.
I'm not sure I'd say that every dialogue should be a battle, but something should change during it. There should be a shift in the balance of power, no matter how subtle.
