Kris Jenner was also interviewed for the feature, telling Vanity Fair: "He was married to me and he wasn't who he wanted to be so he was miserable...
"All I was doing was working very hard for my family so that we could all have a wonderful future, and he was pissed off.
"At the end of my relationship with Bruce he definitely had a lot of social anxiety... That was one of the reasons we were in a struggle at the end."
Kris admitted she was taken aback by Bruce's announcement to become a woman.
"It was like the most passive-aggressive thing I think I ever experienced," she said.
Caitlyn told Vanity Fair Kris knew Bruce took hormones in the late 1980s and told him to stop cross-dressing at home.
The couple separated in June 2013 before officially divorcing in September.
