When it comes to Rob Kardashian and Blac Chyna's current relationship status, it's complicated.
Following the 29-year-old reality star's drama with his famous family on Monday -- when he claimed the Kardashians didn't invite Chyna to a baby shower they were planning and tweeted sister Kylie Jenner's phone number -- a source tells ET that even Rob and Chyna themselves don't see eye-to-eye when it comes to whether or not they're still in a relationship.
"If you ask Rob, he'll say they're having issues. If you ask Chyna, she'll say they are not together," the source says. "Their relationship is not in a good place right now but they are working on it."
Still, the chances of the two reconciling "are pretty high," the source notes.
According to the source, Rob is "in a bad place right now" due to the stress of Chyna being pregnant, as well as filming their new E! reality show, Rob & Chyna. Rob also apparently "wasn't ready" to be back in the spotlight -- after previously being away from Keeping Up With the Kardashians for two years -- but felt pressured to work again and "get his life together"once Chyna got pregnant.
"The stress led to major fights," the source says. "Chyna and Rob are not in a good place right now, which then sets him into a downward spiral."
In a new preview of this Sunday's Rob & Chyna, Chyna notes that Rob has a hard time when around a group of people. When Scott Disick suggests having a barbeque so that the 28-year-old model can finally meet Rob's friends, Chyna is hesitant.
"Do you think it should be a surprise? Because I feel like Rob always gets nervous and chokes up when he's around a lot of people," Chyna tells Scott.
"I don't know none of Rob's friends, and that's just different," she later tells the cameras.
Rob & Chyna airs Sundays at 9 p.m. on E!
Last month, a source close to Rob told ET that "mood swings" were common for the formerly reclusive reality star, after he deleted all of his Instagram posts from his official account -- including snaps of Chyna.
"He goes through his dark periods," the source said. "He gets depressed and doesn't want to really do anything, doesn't leave the house. It got better for a bit when he first started dating Chyna, but he's in a rut now."
