The reggae royalty-former American football player-entrepreneur was previously in a relationship with R&B singer Lauryn Hill, with whom he had five children.
In a recent interview with the international Open Magazine, Marley stated that he still had unresolved feelings for Lauryn Hill.
As it relates to his failed engagement to Brazilian model Isabeli Fontana, the outspoken Marley said he was spending some time alone at this point in his life.
"Now, I am just engaged to myself. It is tough, but we are not to ask ourselves, 'Could you be loved?' but to say, 'Yes, I am loved," he said.
Unlike his brothers, Marley chose to stay away from the microphone. Instead, he took a business approach to the music industry, assisting to transform the Bob Marley brand into an internationally accepted product.
Marley is currently the chairman of House of Marley, Marley Beverages, Marley Coffee, 1Love.org, and the Tuff Gong Clothing Company, among other enterprises.
"I am keeping my father's legacy and ambitions alive, of natural and sustainable ideas, of giving back, of sharing, and of making the world a better place - all the values of a true Rastafarian. I am just a vehicle for carrying on what my father started. He was the first entrepreneur. He ran a recording studio in the backyard, a press implant for pressing vinyls, a record shop, and he made T-shirts. So I am proud to do this. I don't just enjoy it, I fulljoy it," Rohan told Open Magazine.
Bob Marley was recently recognised at the prestigious Grammy Awards ceremony held in the United States. A scene in the 2007 blockbuster film I Am Legend was also dedicated to the late reggae icon. It was narrated by award-winning actor Will Smith.
Marley was only nine years old when his father passed on at age 36.
