How stupid is Adi

How stupid is Adi.He belives anything comes out of Shagun's mouth. Like how that Raman and Shagun's wedding anniversary is today when Raman and his family leave for the party. And Shagun lies to Adi. Shagun and Raman have been separated for long time. So why would Raman wish Shagun happy wedding anniversary when they aren't together. And mostly Raman and Ishita are married.
