Here's how you can distinguish between positive and negative trust. Positive trust is expansive. Negative trust is restrictive. Positive trust is open-hearted and generous. Negative trust is self-protective and punitive.
Positive trust embraces differences.
Negative trust abhors them. Positive trust is largely conscious. Negative trust is largely unconscious. Positive trust grows in depth, appreciation, cherishment and sacredness. Negative trust is stagnant, repetitive, emotionally miserly and deeply forbidding.
