Dreaming about an ex-girlfriend yelling at you can symbolize unresolved feelings or guilt related to that relationship. It may indicate that there are lingering emotions or conflicts from the past that you have not fully processed. The accusation of emotional abuse in the dream could reflect your own feelings of guilt or fear about how your actions might have affected her, even if you don’t consciously believe you were abusive.

The aspect of her gaining weight might represent changes in both her life and yours since the relationship ended. It could symbolize how time has passed, and perhaps how both of you have changed in different ways. This might also reflect concerns about your own emotional state or personal growth since the relationship.

Overall, this dream might be prompting you to reflect on your past relationship, acknowledging any unresolved feelings, and considering how you can learn from those experiences. It could be beneficial to think about what you can take away from this dream to help you grow and move forward.
