betrayal

A betrayal is when someone does something that hurts or cheats another person who trusted them.

When we talk about betrayal, it usually means someone has broken a promise or trust. For example, if your best friend lies to you and says they're going to do something for you, but then doesn't, that's a betrayal of their friendship. It can also be when someone takes advantage of another person in a relationship or situation where there was supposed to be trust. Betrayal is often associated with romantic relationships or close friendships, but it can happen in any kind of relationship where people rely on each other.
