Help your spouse see and understand your thought process as you come to your decisions.
Explain the criteria you consider. How you think about who else may be impacted by the decision. Talk about any risks and trade-offs you assess. Share your priorities, values, fears, goals, dreams and how those all fit into your thought process.
In this way, your spouse will be able to anticipate your perspectives and position for future decisions together.
If your spouse understands that you really don’t like attention, then they can better plan your next birthday celebration.
If your spouse has not really shared how they make decisions, ask. “I want to know you better. Help me understand the thoughts behind that decision. Take me along the thought process.” Tone matters.
