No I havent forgotten. It's just that in the plot it apparently seems more important that her lover betrayed her than that her kin got wiped off. Even in this past episode, the whole focus of the witches was "You should pity her cause the dude broke her heart" rather "You should pity her cause she suffered so much from everyone she knew and loved being killed"
Grannies: "Look at this poor soul. Pity her"
The poor soul: "My ex betrayed me hundreds of years ago so I'm gonna destroy an entire empire of people that have nothing to do with what happened to me to make up for it."
