Rob Kardashian fears that his weight could affect his relationship with Blac Chyna.
In a sneak peek of this Sunday’s episode of Rob & Chyna, the 29-year-old reality star admits to being scared that Chyna will no longer be "attracted" to him because of his weight gain.
Rob makes the confession when Chyna asks him why he skipped her party. "It's a combination of everything," explains Rob. "I just really didn’t want you to see me…and give you more reason not to be attracted to me or whatever. So I just didn’t want to go."
"When Rob says really bad stuff about himself, it kind of like throws me off a lot because I don’t see it," Chyna says to the camera. "And I get it, everybody’s down on themselves and has their opinion, but like some of the stuff he thinks and says, it’s really sad."
While Rob's weight has been an issue for him in the past, the father-to-be credits his pregnant fiancee with pulling him through his "dark days," as he recently told People magazine.
"She got me through the toughest times," Rob admitted. "I wasn't happy in my own skin. I missed out on so many things."
Meanwhile, are the two planning on relocating to the East Coast in the near future?
