And sometimes, the process of divorcing or separating can lead people to discovering all sorts of things they didn't know their S.O. had been hiding or doing throughout their relationship.

Perhaps when you broke up with your boyfriend, you found out he actually always hated your family, and that that played a huge role in why your relationship fell apart.
