Reddit reviews How to Fight (Mindfulness Essentials)

One of the best ways to defuse an argument is to ask for a moment to think. Just a second or two, but intentionally stop talking, give yourself a second to breathe and collect your thoughts. This is doubly effective because mirror neurons will help get your partner into a better headspace as well.

When you start talking again, be sure to acknowledge their view. Echo it back to them as best you can, ask questions to clarify. Be curious about their side, and you may discover that you're not on different sides at all.

I very strongly recommend How To Fight by Thich Nhat Hanh. It's a tiny pocket book and a very easy read.
