Clarify what you need to feel safe and respected. Is it quiet time after work? A budget check-in before large purchases? Naming the request clearly is the first step.
Share your boundary using warm language: “I’d love to talk after I rest for 20 minutes” or “I can stay at the event for one hour.” Offer an alternative so the other person knows you still want connection.
Hold the boundary consistently. People may test it at first; calm repetition and follow-through show that this is about care, not punishment.
