They Repair After Conflict
The most important green flag isn't the absence of conflict — it's the willingness to repair after it. A partner who reaches out after a fight, takes responsibility, and tries to reconnect is showing the behavior that predicts long-term relationship success.
They're Happy for Your Success
When you share good news, do they celebrate genuinely or do they compete, minimize, or redirect to themselves? A partner who is genuinely happy when good things happen to you is signaling security, generosity, and low narcissism.
They Have Their Own Life
A partner with their own friends, interests, and identity is a green flag. It means they're choosing to be with you, not depending on you. Interdependence is healthy; codependence is a trap.
They Treat Service Workers Well
How someone treats people they don't need anything from reveals their actual character. Politeness to waitstaff, courtesy to strangers, patience with service issues — these are more reliable character indicators than how they treat you during the honeymoon phase.
