What was the point in leading Arushi on?

Basicially he lead Arushi on. Aman was the one who asked Professor for Arushi's hand in marriage..

So in a way Aman and Arushi have a " love" marriage

But why does he have to go cheat on her..if you have a supposed love marriage with Arushi and your parents accepted it, then why not your other girlfriend..thats love marriage too,will his parents not accept..

UGH! WHAT A JERK! DON'T LEAD SOMEONE ON LIKE THAT IF YOU DON'T LOVE THEM

STUPID DHONGI!
