Leo is as warm and generous as the Sun itself. Many think you are invincible but there is a kind and vulnerable personality behind that seemingly ironclad façade. You tend to trust people because you believe in the inborn kindness and good nature of others. Unfortunately, it seldom is the case.
You need to remember: your intentions are good, but it doesn’t mean that everyone around you follows the same life principles. Value your trust more; do not rely on people who have not deserved it yet. You needn’t lose faith in humanity altogether, though. Just be pickier when it comes to whom you can trust.
