Finally, things are moving forward. I think ak might tell abhi about abhir. That is her only real guilt and the reason she has been scared all these years. She did not tell abhi anything because she remembers him like he was before, angry and impulsive and taking control of the situation without listening to her. She was scared that if abhi found out about abhir, he would do custody battle, anything to get abhir and destroy ak's life even more. But after his apology, she thinks about how much he has changed (remembers him post-leap). This new abhi is calm. Even when faced with her family life and everything he was calm and even accepted nav as a friend. And she saw how much abhir liked hanging out with him and the bond between them. So now she will tell him about abhir, because she knows he won't react horribly without thinking about the situation. I think he drives away because ak asks him to leave their happy family alone and return to his life. Even though he has a son here, that is best for him and best for her.
