You stop catching up
Remember how excited you used to be to tell each other everything about your days? You couldn’t wait to share every story about your coworkers or your neighbors, or how this or that goal was going. But now, you’re tired. When you get home from work, you want to turn the TV on and your brain off. You don’t want to revisit the day by telling someone else about it. So you stop having proper catch-up sessions with your partner.
