Thinking “I miss my ex” can sometimes lead to a spiral of uninvited thoughts and feelings about a past relationship. Perhaps there is sadness and regret about what was lost or curiosity about what could have been. You might long to be back in a relationship with your ex, and perhaps you might be wondering if your ex feels the same way. Missing an ex is a normal and universal experience. At the same time, everyone heals from a breakup in their own way and in their own time.
