I was thinking about this when I realized everything we know about Adi and Pooja's relationship is from Pooja's perspective, whereas in Adi's FB scenes Pooja and Aditya are very much like a normal couple, Pooja presented Aditya in her diary as a villain, she shared everything with her mother but she didn't care to share anything with her husband, if you want to change something you will make that one attempt to change it, did Pooja make that attempt?
The reason I think Pooja exaggerated everything is the difference between Sakshi's description of Aditya and Pooja's scene about pregnancy news, it seems that Pooja told Sakshi that Aditya asked her to abort the child because he's not ready to take responsibility and he asked Pooja to take care of herself first but it didn't happen like that, Pooja didn't tell Aditya about the baby.
Diary is written from Pooja's point of view and for her Aditya was a villain, at least Yash praised Zoya but Pooja did not write one good thing about Aditya.
