According to flashbacks, Raghav emphasizes on Jhootha pyar and money. So Esha faking her love for some reason is my bet.
Crazy theory alert 
So this Esha loves another man but has some kundali dosh which says that her first husband will die, hence she is afraid to marry her lover. She meets Raghav and discovers that if she marries Raghav, her dosh will be nullified, and even if it doesn't its Raghav (her first husband in that case) who would die and her lover is safe, to whom she can marry later, plus monetary perks. Hence she fakes her love for Raghav but Raghav ends up genuinely falling for her. However things don't go as planned, because Raghav catches Esha with her lover in an intimate setting and gets to know the truth.
Hope I have covered all angles, Money, Fake love, Cheating
