What is why wont my ex leave me alone?

As an AI language model, I cannot know the exact reason why your ex won't leave you alone. However, there are some common reasons why this may happen, such as:

1. They are still in love with you and hope to reconcile.

2. They feel the need to control or possess you.

3. They are experiencing feelings of jealousy or insecurity.

4. They are trying to hurt you or seek revenge.

5. They are unable to move on from the relationship.

If this is a concern for you and you feel unsafe or uncomfortable, it is recommended to seek professional help or talk to someone you trust. It is important to set boundaries and communicate your feelings clearly to your ex.
