Dhadkan (2000)

Wealthy Anjali falls in love with poor Dev. Both want to get married, but her family objects and gets her married to the equally-wealthy Ram, who lives with his uncaring stepmother and siblings. Anjali finds out that Ram is not respected, but does not care as she does not love him. Ram continues to be affectionate toward her and her family, but Anjali cannot get Dev out of her mind. Then things change, when Ram decides to assert himself and asks his family to leave him and his wife alone. Anjali starts warming up to Ram when Dev shows up. He's different now: he's a scheming multimillionaire who will win Anjail over by hook or by crook.
