Long silent treatments inflame spouses. How can you communicate effectively when you are not talking? It helps to be humble, and it feels great to make the first move (once you're made it), so go cuddle your inflamed spouse next time they stop talking, and start stomping.
Peace is far more enjoyable than war, so if you are fighting, its' not about who's right, who's wrong...It's about getting back to peace, and then you can calmly discuss any issues. LOVE feels better than anger.
