Anurag is an ungrateful person

What kind of person Anurag is? In yesterday's episode, how can he not respond to his mother but responds to Prerna when she talked to him. So Prerna is more important than his mother who gave birth to him and raised him.

What has Prerna done for Anurag? Why is she more important than Mohini? She married Mr Bajaj as he was richer than the Basu family. She's a married woman and Anurag is just harassing her.
