The Pakistani cricket legend-turned-politician and the 42-year-old TV journalist announced their decision to split on October 30 amid reports that Imran objected to her meddling in politics.
62-year-old Imran's marriage to Reham was his second after his first marriage with English heiress Jemima Goldsmith for nine years ended in divorce in June, 2004.
Reham Khan, a divorced mother of three, left a job on regional BBC news and moved back to Pakistan in 2013.
Reham said as soon as she and her youngest daughter moved into Imran's mansion in Bani Gala, on a hilltop overlooking Islamabad, she felt stifled.
Her career was a constant problem, particularly when she became an "ambassador for street children" in Peshawar.
"There wasn't any involvement, I never attended meetings or anything of the sort, but obviously there was insecurity," Reham said.
Reham said she gave up her television show to avoid a conflict of interest and did not work for several months.
