But psychologists studying long-term couples have discovered something surprising: compatibility isn't the strongest predictor of whether relationships last. Instead, research points to a specific communication style that distinguishes couples who go the distance from those who don't.

It's about something more fundamental-a pattern of interaction that either strengthens your bond over time or slowly erodes it.
