It's not uncommon for individuals who have ended a romantic relationship to have mixed feelings. Your ex may be saying she doesn't want to completely let you go for a variety of reasons:
Emotional attachment: Even though the romantic relationship has ended, she may still have emotional attachments and feelings for you. These emotions can make it challenging for her to completely cut ties.
Fear of loss: Your ex might be afraid of losing the connection and history you shared. Letting go completely can be daunting, especially if the relationship was significant.
Uncertainty about the future: Breaking ties with someone entirely can lead to uncertainty about what the future holds. Your ex might be struggling with the idea of starting anew without you in her life.
Comfort and familiarity: Staying in touch with you might provide her with a sense of comfort and familiarity, even if she knows it's not the healthiest choice.
Hoping for reconciliation: She might be holding onto the hope of getting back together in the future, even if she hasn't expressed it openly.
However, it's essential to consider your feelings and needs in this situation as well. If you want her to leave you alone and move on, it's essential to communicate your boundaries clearly and assertively. Let her know that you need space and time to heal and that staying in contact is not helping you in the process.
If she continues to reach out despite your requests for space, you might need to take more decisive steps, such as blocking her on social media or limiting any communication channels. Surround yourself with supportive friends and family during this time and focus on your well-being. It's important to prioritize your emotional health and do what's best for you.
