Why do I keep thinking about my ex even though I know they were wrong for me?
Relationships & Divorce
Thinking about an ex is normal because your brain is processing the loss and trying to make sense of the relationship's end.
Your brain doesn't distinguish between a good relationship and a bad one when it comes to processing loss. Even if you logically know your ex wasn't right for you, your mind is still working through the Attachment theory, the habits, and the future you had imagined together. This is especially common if the relationship had intermittent reinforcement - moments of connection mixed with conflict. Be patient with yourself as your brain processes this loss. The thoughts will become less frequent and intense with time.
