There could be several reasons why your ex calls you and shares details about her personal life:
Emotional connection: Even after a breakup, some emotional connection may still exist between you two. Your ex might feel comfortable talking to you because of the history you shared, and she sees you as someone who understands her.
Seeking validation: Sharing personal details with an ex can be a way for her to seek validation or attention. By confiding in you, she might be looking for reassurance or a sense of importance.
Friendship: She could genuinely value your friendship and trust you as a confidant, especially if you had a strong bond before the romantic relationship.
Regret or remorse: If the breakup was difficult for her or if she initiated it, she might feel guilty or regretful about the decision. Sharing her personal life could be a way to maintain a connection or keep you in her life in some capacity.
Feeling lonely: Your ex might be feeling lonely or going through a tough time, and talking to you offers her a sense of comfort and familiarity.
Comparison: Sometimes, people share their personal lives with an ex to indirectly compare their current situation with how things were when they were together.
Mixed feelings: Breakups can be emotionally confusing, and she might be trying to process her feelings by talking to you.
Insecurity: By sharing her life, she might be trying to show that she is doing well or moving on, hoping to evoke a reaction from you.
It's essential to be mindful of your boundaries and emotions in such situations. If her calls make you uncomfortable or interfere with your healing process, consider gently setting boundaries or reducing contact until you feel ready to engage in a more supportive way. Remember that it's okay to prioritize your well-being during the post-breakup period.
