What is he led me on and broke my heart?

It is unclear who "he" is referred to in this statement, as there is no specific person mentioned. However, being led on generally refers to a situation where someone gives the impression that they are interested in a romantic relationship or pursuing someone, only to end up breaking their heart by suddenly ending the relationship or revealing that they were not truly interested. This can be a painful and confusing experience for the person who was led on, as they may have invested time, emotion, and resources into the relationship. Recovery from a broken heart can take time and may involve seeking support from friends, family, or a therapist.
