Dil To Pagal Hai (1997)

Nisha is an actress in a play that is being directed by her sweetheart, Rahul. The only problem is that Rahul has no time for her or romance. When Nisha becomes sick, and has to go off for a few weeks, she is certain that everything will collapse after her departure, and is also sure that Rahul will miss her terribly and come right to her. This does not happen. Weeks later, after recovering she returns to the rehearsals and the theater, only to find that everything has changed. Rahul has replaced her with a new actress named Pooja, who he is very obviously smitten with, and none of the caste and crew really seemed to have missed her. She is quite depressed at this, but cheers up quite a bit when Ajay makes his entry. For Ajay is none other than Pooja's betrothed, and they will be marrying shortly, leaving the field clear for Nisha to have Rahul for herself.
