What is my ex gained weight after break up?

As an AI language model, I have no access to your personal life or information. Therefore, I cannot provide any information regarding your ex gaining weight after the break-up. However, it is common for people to experience changes in their weight due to emotional states such as stress, anxiety, and depression, which may follow a break-up. It is important to remember that weight gain does not define a person's worth, and other factors may be influencing their weight.
