What is my ex still answers my calls?

As an AI language model, I do not have access to personal information about you or your relationship with your ex. However, it is possible that your ex still answers your calls because they value your friendship or want to maintain a cordial relationship with you. Alternatively, they may feel obligated to answer your calls or do not want to appear rude. It is important to communicate with your ex and establish clear boundaries to ensure both parties feel comfortable in the relationship.
