My best friend is currently going through a breakup. She and her ex weren't of the same religion, so they decided to part ways. Yesterday she was telling me that she feels like she can't talk about her feelings with me because I don't understand. I was hurt when she said that she can't confide in me, but maybe she's right — maybe I don't fully understand how she feels.
My friend says she's always reminded of her ex, whether she's happy, sad, angry, or feels any other emotion for that matter. She says that she's sad by default and that's how she's felt for months. Outwardly, she seems fine, but deep inside, she's just sad. What's the best advice that I could give her? Is it possible to never get over someone because you've had something really magical — something you've always wanted? Is the way she feels even normal?
