Why did Zhao Linger break up with Li Xiaoyao?

First, Linger couldn't control her body and turned into a snake (it is said that Nu Wa is like this, Linger is a descendant of Nu Wa's family, and she lost her mind after pregnancy and showed her true colors). She couldn't face herself, and she was afraid of scaring Xiaoyao brother, so she had to leave.

Second, when Linger left, she should not know that she was pregnant.

This is the plot of the game. This TV play was randomly adapted and created many illogical jokes. It's normal not to understand.
