When Gu Xijue saw that the family arguments were minor and he had already expressed his stance, he told Zhao Ying that if she wanted a divorce, she could have it at any time.
If Zhao Ying didn't have the guts, she wouldn't keep fighting with Gu Qingyuan like this.
Gu Xijue wanted to find an opportunity to talk to Gu Qingyuan about Gu Xiaonuan, but due to Zhao Ying's issues, he couldn't.
Zhao Ying is home every day now, and if Gu Xijue speaks, it would directly provoke Zhao Ying.
If Zhao Ying is greatly provoked, she would chase Gu Xiaonuan at the hospital to cause trouble.
The reason Gu Xiaonuan is hospitalized is emotional; she has been greatly stimulated, hence she sealed her thoughts in her own little world.
If Zhao Ying went to the hospital to cause a scene at this critical point, Gu Xiaonuan might be even less willing to emerge from her little world.
