He fell in love with Vanraj, the day Vanraj decided to not leave his hand and jumped with him from the cliff.. Put your hand on your heart and think about it.. Will Anupama ever do this for Anuj what Vanraj did for him? She will walk up to the cliff where Anuj is hanging, give expressions as if she wants to save him, but will not even hold his hand to pull him up thinking about the inconvenience that will be caused to Baa, Bapuji, Tosu, Kinjal, Sweetudi etc if she vanishes away from this Earth. However, Vanraj not only risked his life to save him but also took him on a crazy, high-speed long drive before taking him to that dreaded cliff... 
Today Anuj is just scared that if he asks Anupama to limit her visits to SH, he will also lose his access, to take a look at the handsome face of Vanraj, who till now was just a lady killer, but now managed to make even a billionaire gasp for breath. I don't think it's fair to blame him. Love just happens. The heart wants what it wants.. Otherwise, why would he even try to butter Baa... Of course, there are hidden feelings attached to his behavior...
