betrayal of trust

Breaking a promise

Betrayal of trust is the violation of confidence someone has placed in you.

The phrase emphasizes the relational damage—not just that harm was done, but that it came from someone granted special access or responsibility: The affair was a betrayal of trust that ended their marriage.

It applies to personal relationships, professional duties, and institutional obligations alike.
