I watched barfi and I have lots of questions!!

I don't like bollywood movies except some like Rajkumar hirani movies, Aamir khan movies, Rockstar, Masaan, Dangal and few more.

Movies with cheating or glamours are not my type.

I recently watched "Barfi" and I have lots of questions.

1. Shruti (mrs.Sengupta) was engaged to a man she loved, then why the heck she was roaming with barfi and kissing him?
2. After jhilmil lost, how the heck shruti use that opportunity to live with barfi? Barfi just lost his jhilmil, then why he take shruti and live with her?
3. After barfi found jhilmil, they shows the photos of barfi, jhilmil and shruti. what's the role of shruti? All three live in same home? As a friend or something else?

I hate movies when they promote cheating or objectifying. That's the reason I hate bollywood.

I liked this film but I couldn't get these things. Am I missing something?
