The Murder 3 actor dated the former Miss Universe for three years.
He told The Times of India: "I was not in a relationship with 'Miss Universe' and did not feel a sense of conquest in any way. The biggest part in my relationship with her over three years was my relationship with her daughter Renee.
"I missed only one theatre rehearsal in my life as Sushmita wanted me to not go and that is the worst thing I did in terms of my value system. I was exposed to fame although I was on the sidelines as I was not a star.
"The break-up was the best thing that happened to me and I realised that I gave it too much time in my life. It freed my energy to do things for myself."
Hooda has previously admitted that he was out of work before being cast in Once Upon a Time in Mumbai.
It was reported in 2011 that the star's fiancee Neetu Chandra postponed their wedding because he appeared in too many sex scenes.
