John, 38, dated Basu for ten years and the couple split rencently.
"I have become mature in life. I must say that every relationship helps you to grow in life and makes you mature.
If today I am sitting here and discussing about my personal life which I had never done before, you can easily gauge that how much I am enjoying my space and time now," John said.
"I am happy that now I have time for myself and my ailing parents. They are not keeping well and I am devoting all my time to them," he added.
Professionally also John is enjoying the current phase of his career. He believes his forthcoming release `Force`, Tamil remake of `KaakhaKaakha`, will enable himself to make a mark in the genre of hardcore action.
"After `Dhoom`, I`ve not attempted any action film. So, my fans were a little disappointed with me. Many pointed out that I have the physique and strength, therefore I should attempt a hard core action film. And post this film I think people will find me in the action hero slot," John said during a Van Heusen store launch in the Capital.
But he says, it was not intentional to join the league of action heroes of Bollywood.
"I think it`s all a sheer coincidence that I am playing the character of a cop. We had never planned that all of us will play the character of an outrageous cop. But I feel Salman bhai and Ajay Devgn have brilliantly don the character," he added. .
