Gu Xiaonuan wasn't ignoring Si Yuchen, but was waiting for Si Yuchen to recover on his own.
Gu Xiaonuan had also experienced pain and despair, and when she had lost hope in everything, she didn't want comfort and support from those around her; she just wanted to be quiet, to think about the future alone.
Gu Xiaonuan could equally feel Si Yuchen's pain and despair at this moment, wanting him to give up Mu Shan just like she did. Although he didn't show difficulty, he was suffering inside.
The reason Gu Xiaonuan was willing to give up Gu Xijue was that she had started thinking differently than before.
She needed to think about what was best for her child, rather than placing herself at the forefront of her considerations about gains and losses.
Xi Nan found Gu Xiaonuan's attitude genuinely frustrating, but Gu Xiaonuan had her own thoughts and judgments.
