Who is Harleen's father?

Who is Harleen's father and what did Jasmine do to Yash's brother? 

Harleens father is some rich man who Jasmine married after returning to India, im not sure if they have shown him or not

Jasmine was in a relationship with Yashs brother, but when he couldnt fulfil her dreams she broke his heart and he committed suicide. (i dont remember character names, but im guessing Yash is Naaz father right? The man Jasmine married to go to Canada but he was just taking revenge from her for his brother)
