What is the reason why the pure princess and queen broke up in The Story of Yan Xi Palace?

After learning that Fu Heng had no feelings for herself, Chunfei thought that her persistence over the years was a joke, so she broke with the Queen.

When she was young, she gave Fu Heng a love letter and an ear. When she saw Fu Heng wearing it, she mistakenly thought that he liked herself, so she was very kind to the queen, straightened her position and took good care of her. In fact, the pure princess did it for Fu Cai Heng willingly.

But I don't want my love letters to be sent to Fu Heng at all, and all this is because the girl Yuhu around me knows that they are predestined friends and will destroy those letters without authorization. After all, her goodwill was wrongly paid, and Chunfei gradually gave birth to the idea of competing for favor.
