The Biology of Trust After Betrayal

Notes from the Edge

Why is it so hard to trust again after betrayal, even when you know the danger has passed?

In this episode of Notes From the Edge, Lisa Lacy explores the biology of betrayal and why healing is about so much more than “letting it go.”

Together, we’ll explore:
• Why trust is a biological prediction, not just an emotion
• What happens inside the brain and body after betrayal
• Why attachment and fear can exist at the same time
• How survival strategies become identities
• Why hypervigilance, people-pleasing, and emotional numbness are often adaptations rather than personality traits
• How trust can be rebuilt one safe experience at a time

If you’ve ever questioned yourself after infidelity, emotional abuse, manipulation, or repeated violations of trust, this conversation is for you.

You are not broken.

Your survival system has simply been trying protect you. 

What did you perform in order to survive?

These are the conversations we should have been having all along.

Welcome to the Edge.
