The phrase "create our own heartbreaks" suggests that our expectations can lead to disappointment or emotional pain. When we have specific hopes or demands for how a situation or relationship should unfold, and those expectations are not met, it can result in heartache.
The key element here is "expectation," which refers to the anticipation or belief that something should happen in a particular way. Expectations can set the stage for disappointment because they create a rigid framework that reality doesn't always adhere to.
In essence, this statement serves as a reminder to approach relationships and life with a degree of flexibility and openness. While it's natural to have expectations, it's important to recognize that they may not always align with reality. By managing our expectations and embracing the unpredictable nature of life and relationships, we can reduce the potential for self-inflicted heartbreak.
