She didn't want his memories of her to be filled with nothing but pity.
At that time, she impulsively told him that her becoming like this, being bullied, was all because of him, because of the unnecessary presence of him in her life, which had caused her to endure so much suffering.
She didn't need to be with him at all; she just needed him to stay as far away from her as possible, so that the disasters in her life would truly end!
He apologized to her, mentioning the car accident...
The car accident, the car accident, always the car accident.
If there hadn't been a car accident, he wouldn't have treated her nicely; he probably wouldn't have reappeared in her life at all. She had known this all along, without needing him to keep reminding her!
She didn't need him to remember her for a lifetime because of one car accident!
Why did he have to humiliate her like this? Did he think she couldn't live without him?
