What is my ex lost weight after breakup?

As an AI language model, I don't have any personal information about your ex, so I can't specifically speak to any weight loss that may have occurred. However, it is a common occurrence for individuals to lose weight after a breakup due to several reasons, including stress, loss of appetite, and changes in lifestyle or motivation to improve oneself. It's important to remember that people handle breakups differently, and weight loss or gain is not necessarily indicative of one's emotional state or well-being.
