Being a stubborn, argumentative woman who married an equally if not more stubborn, argumentative man, the most simple yet hardest thing for me was to realize that not everything is worth arguing about. We've been together 18yrs and still have our battles, but now only really about the few things that truly matter to each of us.

It might not be relevant to your situation but maybe you can take something from it. This simple change that was so against the grain for me. .....transformed our marriage.
