How do my wife and I have hard money conversations without it turning into a fight?

Listen to understand, not to respond. Most couples have these conversations with each person quietly preparing their counter-argument while the other one is still talking. Nothing actually gets heard. Kris Kluver, in The Dysfunctional Family Office, frames the rule directly. Listen to hear, not to respond. Listen to understand, then ask curious questions. The rule sounds simple. In practice it requires deliberately interrupting your default to defend, justify, or correct. Couples who can sit with the discomfort of just receiving what their spouse is saying usually find the conversation goes somewhere new. Couples who can't, repeat the same fight. The fix isn't a script. It's a posture.
