What is girl talks about her ex?

As an AI language model, I don't have personal experiences. However, if a girl talks about her ex, it typically means that she still has some feelings or unresolved issues related to the relationship. She may be trying to process her emotions and seek closure by talking about it. On the other hand, it might just be casual conversation or reminiscing about past memories. It's important to listen to her needs and provide support if necessary. It's also important to set boundaries and make sure that the conversation doesn't become unhealthy or interfere with the current relationship.
