A timeline of Rob Kardashian and Blac Chyna's contentious, tumultuous relationship

Rob Kardashian blasted his on-again-off-again girlfriend and mother of his child, Blac Chyna, Wednesday on Instagram — and later with the same posts on Twitter after, as he explained, “Instagram shut me down” — with allegations of infidelity and drug abuse. In a series of posts, the youngest Kardashian sibling shared explicit photos of his ex and shared details of her alleged sexual relations with multiple men. (Blac Chyna’s lawyer said he was exploring “all legal remedies and protections available to my client” in the wake of Kardashian’s revenge porn posts.)

This isn’t the first time the couple has gone through a very public fallout — indeed, the course of their love has never really run smoothly. Here’s a timeline of the sparring ex-lovers’ relationship:

Where it all began…

On Instagram, where the trouble came to a head on July 5. But before that, on Jan. 25, 2016, Chyna shared a since-deleted (get used to hearing those words) photo on the social media platform in which she was being hugged by a heavily-tattooed arm. She captioned it simply: “The beginning.” It didn’t take long for fans to speculate that the inked arm belongs to Rob Kardashian. Still, not everyone believed it could be him, considering Chyna has a son with rapper Tyga, who, at the time, was dating Kardashian’s half-sister, Kylie Jenner. Chyna had previously also been close friends with Kim Kardashian, though things seemed to shift after Kylie and Tyga started dating.

Public declarations

A few weeks later, Rob made a show of his love for Chyna, showering her in dozens of roses for Valentine’s Day. A few days later, the reality star splurged on a Calabasas mansion for them to live in together, and within a couple weeks he declared his love for Chyna in a since-deleted Instagram post: “Love this woman right here so f— y’all with your negative comments.”

The good life

For a moment it seemed like things were going well between the twosome. Rob, who had previously struggled with physical and emotional wellbeing, began to adopt a healthier lifestyle, fitness regimen, and a generally more positive outlook. However, it’s short-lived when in March 2016, Rob purged his Instagram account of any trace of this life-changing lady friend. Rumors swirled that the couple had parted ways, prompting Rob to once again to clear the air on Instagram. “Chy and I are not broken up we just feel like it would be a lot healthier for our relationship if we kept a lot more to ourselves,” he wrote. “It’s impossible to have a positive relationship with so much negativity from the media and outsiders and we would appreciate if it everyone respects that.” He also invents the couple name: ChyRo.

Smooth sailing

Later that month, the couple jetted off to Montego Bay, Jamaica to soak up some sun. A week later, Rob attended a birthday party for his mom, Kris Jenner. By the end of the month, the Kardashians have begun to embrace Chyna as part of the family, acknowledging her positive influence on their brother and son’s life. Across social media platforms, all was well, with their snaps even getting a little racy at times.

Better put a ring on it

After ten full weeks of dating, the couple announced their engagement. The 7-carat diamond ring was designed by Rob’s childhood friend. The lovebirds celebrated their impending nuptials at L.A. gentleman’s club Ace of Diamonds.

And baby makes three

On May 6, 2016, the couple confirmed on Instagram that they were expecting their first child together.

Natural progression

The couple settled comfortably into their pregnancy and further bridged any gap between Chyna and the rest of the Kardashian/Jenner brood. Naturally, that prompts E! — home of Keeping Up with the Kardashians — to green-light a new reality show documenting their life together.

Purge, take two

By July 25, 2016, Rob once again purges his Instagram of all traces of his Blac Chyna. People weren’t sure what to make of his actions, especially when the model shared a makeup tutorial on Snapchat, her gleaming engagement ring in full sight. Rob followed up by going on a blocking spree, preventing calls from his sisters as well as his fiancée. In September, Blac Chyna tweeted out Rob’s cell phone number, adding on Snapchat: “To assure your man is not texting no bitches, just tweet his number out. How’s that feel Rob? How ya feel?…Get your number changed, thank you.”

Baby’s here!

The troubled twosome (back together or never apart?) welcome their first child together on Nov. 10; they name the baby girl Dream Renée.

The beginning of the end

With their child a little over a month old, things started to go wrong between the feisty couple in December. On social media, Rob revealed that Blac Chyna has taken the baby and left him. On Snapchat he claimed Chyna “took the baby, took the whole nursery we built” while sharing images of empty rooms in the couple’s home. He added that Chyna wasn’t letting him see their daughter. “She blocked me or else I would ask to see her and she has the guard gate not letting me in the gate either. I just miss baby Dream.” In a since-deleted post, Chyna says Rob could come and see Dream if he wants to because he “knows where we are.” This all went down after screenshots of private messages Chyna had sent, in which she insults Rob, appear on her apparently-hacked Instagram account.

New year, new start

After a tumultuous holiday season (including a brief hospital stay for Rob, who is treated for problems related to his type 2 diabetes), the back-on couple spent New Year’s Eve together, enjoying a romantic dinner with their daughter. On Jan. 25, the new parents celebrated making it to their 1-year anniversary. Naturally, they shared a photo of the occasion on Instagram. “1 year down lol woohoooooo happy anniversary babbbbbbiiiiiiiieeeeeee,” Rob wrote in the caption.

Never mind…

In February 2017, the couple is off again with reports citing Chyna’s intolerance towards Rob’s insecurities and depression as the main reason for the split. Terms like “custody battle” start to surface, with sources expecting the fight for Dream to get ugly.

Are they or aren’t they?

A couple of months later, the “we thought they broke up” couple is spotted at a restaurant and on May 30, Rob uses his favorite communication tool (Instagram, in case you hadn’t noticed the trend) to write a sweet note about the mother of his baby. The since-deleted post reads: “On my first episode of Rob’s Random Cornball Thoughts is This young lady who grew up to be the woman I love and the mother of my child.” But then just one day later…

New flames

It looks as if Rob had moved on, as rumors circulated that he was dating Mehgan James (Oxygen’s Bad Girl’s Club and VH1’s Basketball Wives LA). Rob denies the claims and it seems he and Blac Chyna are getting along well enough for the sake of their daughter.

Fireworks

Then, on July 5, Rob dragged Chyna (yet again) through all kinds of dirt for her alleged behavior on his since-deleted Instagram account. In many explicitly graphic posts crammed with insults and expletives, the Keeping Up with the Kardashian star accused his ex of sleeping with three men (himself included) in one weekend. “Hahahaha Chyna just sent me this video saying happy 4th of July what a crazy person,” he captioned one video in which Chyna is kissing an unidentified man. “Come spend time with your daughter … ” He went on to share a screenshot of an alleged text conversation between them, which includes a photo of her exposed genital area. (Instagram — which does not allow “nude, partially nude … pornographic or sexually suggestive photos or other content via the Service” — suspended his account.) But that didn’t stop Kardashian, who took his rant to Twitter, re-posting the explicit photos — which EW does not include below — and reiterating accusations of his ex’s infidelity.
