I beleive yes they both did deigo wrong but imagine being nearly 100 years old inside your head with a body of a young adult, who has never loved anything more than a mannequin. Who already suffered being alone for 45 years in nothing else but destruction and survival.
Deigo was treating lila like sh×t and he lost himself. As much as lilas kids mattered, their marriage was going to sh×t and lila deserved better. I believe five gave her a glimpse of better and treated her a whole lot better than deigo did.
Also being alone for 7 years with somebody would mean you would have to survive together and that would mean seeing that person's bad days and good days, and seeing somebody truly for who they are and also being able to only see that person would make u love them. Or that, bordem and lonliness would adventaully catch up and make u want that person.
Tbf I shipped them before even seeing a connection between them, and I believe lila and deigo were a bit toxic from the start.
What does everyone else think?
