'Keeping Up With the Kardashians: About Bruce': Kris Says She Has to 'Mourn Bruce'

— -- On Monday night's Part 2 of the E! special "Keeping Up With the Kardashians: About Bruce," the world finally got to see Kris Jenner and her ex-husband Bruce deal with the emotional fallout of his decision to fully transition.

Though Kris, 59, wanted to be supportive, she admitted, "It's really hard for me to wrap my head around it."

The Kardashian matriarch -- in a tearful chat with her ex of more than 20 years -- added that she felt like Bruce died, because he planned on becoming a woman.

"I have to mourn Bruce Jenner," she said. "I miss Bruce ... I'll never be able to have Bruce and all I'll have is my memories."

Kris was confused as to what happens to the former Olympian after he transitions. He replied that he'll still be around.

"I still love you baby," Jenner said.

"Hopefully, I'll be a better person and happier ... I want you to be happy," he added.

Bruce, 65, and Kris also brought up the fact that a few times in the past they had similar conversations because Bruce was unhappy, but Kris said not until now did she know exactly what was wrong.

"I think you shut me out a long time ago," Kris said.

Bruce added that he felt Kris "treated me badly" those last 4 or 5 years of marriage.

The emotional conversation ended with Kris telling her ex: "I just want you to know you were a great dad ... a great partner ... It's about you and I just want you to be happy."

Meanwhile, Bruce sat down with his girls -- Kim, Kourtney, Khloe, Kendall and Kylie -- to address any added questions they had about his transition.

Kourtney brought up the question of when Bruce would fully become a woman, like does he just "pick a day, like 'This is the day I'm going to just wear this stuff," referring to women's clothes.

Kim followed that up by asking if Jenner had any surgery planned to fully make him a woman.

"Oh, the little thing down there?" he candidly responded.

"That's kind of the last thing you can do," Jenner said, adding that he does not have a plan to have sex change surgery at the moment of the taping a few months back

As for dating post-transition, Bruce added that he's "not doing this for that reason" and that he is heterosexual, but has no plans to date.

"Right now I am very optimistic about the future and I haven’t felt that way in a long, long time," Bruce added.
