What is my ex stopped posting on social media?

As an AI language model, I don't have access to your personal details or your ex's social media accounts. However, there could be several reasons why your ex has stopped posting on social media. It could be because they have lost interest in it, or it could be due to personal reasons such as a breakup, a change in their lifestyle, or a busy schedule. Whatever the reason may be, it is important to respect their privacy and give them the space they need. Remember, social media is not always a reflection of someone's true self or the reality of their life.
