Why it makes you better company
Most of us spend our days in a state of low-level attunement to other people — anticipating what they need, monitoring moods, adjusting. It's a genuine skill, and it is exhausting precisely because it never announces itself as work. Time alone, by choice, is the only reliable way to switch that channel off. You stop asking "is everyone all right?" and start noticing what you think about things.
What people find surprising is the effect on the relationship at home. Coming back with something of your own to talk about is enormously more interesting than coming back with a list of what's left to do. Partners who initially bristle at the idea tend to come round quickly, and often start taking their own evening. A household in which two people occasionally leave and return with news is a livelier household than one in which nobody ever goes anywhere.
How to make it actually happen
Put it in the calendar like a dentist appointment, same slot every week, because floating intentions get eaten by everyone else's needs. Two hours is plenty. Tell the household in advance, plainly and without apology or justification: "Thursday evening I'm out." Explanations invite negotiation; statements don't.
