Speaking as someone who’s parents when waited to get divorced until I went to college, I think I would have been less messed up if they’d been honest and mature enough to get divorced when they’d wanted to.
Speaking as someone in that same boat, I appreciate my parents kept a semblance of a family for my entire childhood. Hearing my friends who did not have that makes me understand that even my childhood with all of the fighting and arguing was better than that of my peers who did not have a good relationship with one or both of their parents
