According to reason, one should persuade reconciliation rather than separation, but the gap between Xingyun and Shaohua is too large.
They are not together out of love, and if they stayed together for the child's sake, it wouldn't last long.
Moreover, there is a Song Yi between them, so they wouldn't be happy.
Given this, it would be better to divorce sooner rather than later.
"In-law, since you asked, I won't beat around the bush. Shaohua is the only son of the Huo Family and he has only one child, Tianxin, so the child cannot be taken away by Xingyun. I won't allow them to divorce," Grandma said sternly, putting away her smile, prioritizing the Huo Family.
She indeed liked Xingyun very much, but Tianxin is the descendant of the Huo Family and couldn't be taken away by Xingyun.
If they must divorce, then she would personally take care of Tianxin.
She wouldn't let Song Yi harm Tianxin.
