Are Rob Kardashian and Blac Chyna back together?

Fans are having a hard time keeping up with the on-again, off-again couple — but judging from Chy’s latest Instagram post it looks like there’s no hope at rekindling their romance.

The 29-year-old shared a text post and made it very clear to her 12 million followers that she is done with Rob. The post read “Single. [I’m] happy,” and she simply captioned the post with, “Hello.”

Her new relationship status may come as a shock to fans, especially since Chyna and Rob looked happy as they celebrated his first-ever Father’s Day together after welcoming their first child — a baby girl named Dream — last November. They posed next to Minnie Mouse in an adorable family photo — but a source exclusively revealed to Life & Style that their smiles were just a front.

“Rob and Chyna could not stop bickering as they made their way around Disney,” the witness revealed. “They were sniping at each other the entire time.”

Despite their arguing, Rob, 30, reportedly went back home with Chyna and Dream and never left — and a source revealed to People that the couple was trying to work things out again for their daughter. But even though they were together for a short while, it looks like things ended pretty quickly.

“They are both complicated people. It’s very possible they will get back together,” the insider said. “But it’s also possible that they will have another epic fight. For now, things are peaceful and everyone is happy.”

Even though they couldn’t work it out this time, they were together as a couple pretty recently. Back in April, Chyna and Rob cuddled up together in a series of video posts on her Snapchat. In one clip, Rob wrapped his arms around Chy’s tiny, post-baby waist — and she captioned that particular shot, “Dream’s daddy.” They posed together for the next shot and Chyna asked Rob to give her a kiss and he did — planting one right on her chin.

The couple has been dating on-and-off for a little more than a year, and they got engaged after three months of dating. The tumultuous nature of their relationship was documented on the first season of their show, Keeping up With the Kardashians spinoff Rob & Chyna, where they aired out all of their problems — which mostly stemmed from Rob’s insecurities.

After the birth of Dream, it seemed like things were going well for the couple. But they had a very public breakup less than one month later and Chyna allegedly packed up her things and left Rob — taking their daughter with her.

But like most of their breakups, that one was short-lived and they were back together by New Year’s Eve. Their most recent break up happened in February, but Rob and Chyna were able to keep things civil and she even attended his birthday party in March — and she brought little Dream along with her.

It’s unclear if Chy is really done with Rob for good this time, but in an interview with Cosmopolitan South Africa back in March, she said that despite all their breakups, she’s committed to making their relationship work.

“I feel like every person who’s in a long-term relationship, or who is committed to their person, goes through ups and downs,” she said. “Everything isn’t always going to be peaches and cream. If it is, then it’s fake. I’m in it for the long haul.”
