Why breakups hurt

What You’ll Find in This Chapter

Breakups don’t just hurt—they tear through your brain, your identity, and your sense of safety. In this chapter, we dive deep into the science and psychology behind that pain. We’ll start with the biology of love and loss, exploring how your brain reacts to a breakup like it’s been cut off from a drug. Then, we’ll uncover how attachment styles shape your breakup experience, from anxious spirals to avoidant shutdowns.

From there, we’ll look at the psychology of rejection, why it hits so damn hard, and why closure feels like chasing a ghost. We’ll tackle the endless rumination loops that keep you stuck in the past, and finally, walk through the grief stages your heart tries to survive. This ain’t just heartache—it’s a full-on emotional battlefield, and we’re here to map it out.
