Heartbreak is a subconscious decision of the Self to experience pain by living through its early childhood trauma. It’s pretty much impossible to stop that wheel of repetitive events in your life - they are attracted to you in order to fill up the emptiness inside of your “broken heart” (event in the early childhood usually before 5 years old).
