Describe what partnership means to each of you
Living together, sharing money and caring for relatives are separate choices. Ask which responsibilities you each consider shared and which you want to keep individual. Do not assume that a label answers those questions for you.
Choose a decision with real consequences
Talk through one issue you are facing, such as dividing time between families or taking on a new expense. Explain what you need and what you are flexible about. If you cannot agree tonight, name the information or time you need next. Understanding the disagreement is progress even when a decision takes longer.
