Kris Jenner thinks she "failed" Bruce Jenner.
The 59-year-old matriarch is reportedly devastated she didn't do more for her ex-husband when he made the decision to become a woman.
A source said: "That interview made her think twice about herself and she thinks she's failed miserably as his wife.
"Hearing Bruce say that they would still be together if she were able to handle his transition better than she did sent chills throughout her entire body. She feels she failed him."
But Bruce, 65, is said to have promised her that she was "the perfect wife".
An insider added to HollywoodLife.com: "Bruce assured her that she didn't fail him and told her she was 'the perfect wife' and that 'everything happens for a reason'.
"He begged Kris to not feel guilty and reminded her that some of the best years he spent as a man were with her."
Meanwhile, Kris and Bruce's children Kendall and Kylie Jenner have tweeted their support for the former Olympian.
Kylie wrote: "I'm very proud of the man that gave me everything I have, he's my inspiration to be strong every single day no matter what, I love you dad (sic)"
Whilst Kendall added: "Dad.. It's been a tough road, but I'm proud of you and I'll always be. I couldn't ask for a better dad, you're such a rode model to me ...
"No matter what my dad will always be my hero. Nothing in my life has been as difficult as this. Thanks for all the love and support y'all have given to us but specially to my dad in this big step in his life. May god always bless you."
