There could be several reasons why your ex-girlfriend is still talking to you even if she is seeing someone else. It's important to remember that every individual and situation is unique, but some common reasons might include:
Friendship: Some couples are able to transition from romantic partners to friends after a breakup. They might still value each other's company and want to maintain a platonic relationship.
Emotional connection: If you had a deep emotional bond during your relationship, it can be challenging to sever all ties immediately. Your ex-girlfriend might still feel connected to you on an emotional level and want to stay in touch.
Closure: She might be seeking closure or trying to understand why the relationship ended. Talking to you could provide her with a sense of understanding or acceptance.
Comfort and familiarity: Being in a new relationship can be both exciting and daunting. Your ex-girlfriend might find comfort in talking to someone familiar while navigating a new romantic connection.
Keeping options open: Sometimes, people maintain communication with their exes as a backup plan or in case their current relationship doesn't work out. This isn't an ideal situation and can lead to complications.
Unresolved feelings: She may still have unresolved feelings for you, even if she is seeing someone else. These feelings could be contributing to her desire to stay in contact.
Guilt: If the breakup was difficult or if she initiated it, she might feel guilty and want to offer some form of support or friendship as a way to alleviate her guilt.
Mutual friends or shared interests: If you have mutual friends or share common interests, she may feel the need to maintain some level of communication due to these connections.
Regardless of the reasons, it's essential to approach the situation with caution and communicate openly about your boundaries and feelings. If you're uncomfortable with the continued communication or if it's interfering with your ability to move on, it's okay to express your concerns and consider reducing or ending contact for a while until both of you have had time to heal.
