Gu Xiaonuan would never give up on her marriage with Si Yuchen, especially now that she finally realized Si Yuchen's goodness.
Because she realized it, she no longer wanted to abandon the hard-earned relationship.
This relationship, not to mention how much time it had already cost Gu Xiaonuan, stems from her own desire not to let things go sour with Si Yuchen again.
Si Yuchen has his own thoughts, but he also has his own heart.
Si Yuchen is not the kind of man Gu Xiaonuan can have just because she wants him, or catch and hold onto just because she desires to.
Si Yuchen has his own independent judgment, and this judgment gives her a sense that she should not miss the opportunity again.
Perhaps Gu Xiaonuan truly feels that Si Yuchen might leave her for someone else, which is why she thinks this way.
Gu Xiaonuan is filled with insecurity, worrying even before she loses anything.
