The fighting seems to have ceased for now, but Rob Kardashian‘s ongoing battle with his inner demons is hurting his relationship with Blac Chyna.

In a sneak peek at Sunday’s new episode of Rob & Chyna, the reality star admits to feeling anxious over his weight and fears his fiancée won’t be attracted to him anymore.

“It’s a combination of everything,” Kardashian tells Chyna in the clip after skipping a party she hosted. “I just didn’t really want you to see me and give you more reason to stop being attracted to me or whatever. So … so I just didn’t want to go.”

The 29-year-old’s confession pulls at Chyna’s heart strings as she tries to understand why he feels this way about himself.

“Even though I’m pissed at Rob for ghosting on me, when Rob says like really bad stuff about himself … it kinda like throws me off a lot because I don’t see it,” she says in an interview. “And I get it everybody’s like down on themselves and have their opinions, but some of the stuff that he thinks and says is really sad.”

“I think we should get together and talk,” he tells her.

In a second clip, the pair wind up sitting down and hashing things out, but Kardashian still doesn’t feel ready to move back in with Chyna.

“Well, I accept your apology, and thank you,” Chyna, 28, tells him. “I think that we’re all good, and I think maybe you should come back to the house.”

“I’m not trying to be up in your space,” Kardashian tells her. “I want to keep this time for us to get our own s— together and move in a good direction. I think where I’m at right now is a good thing for us.”

“There’s lots of things I need to work on for myself, so I feel it’s best if we give each other some space so I can work on me,” he explains in his interview.
