It seemed like things were finally getting better for Rob Kardashian and Blac Chyna following the birth of their daughter Dream last month, but in a shocking twist, the couple appears to have once again broken up, this time for good.

Kardashian revealed the news in a Snapchat video over the weekend, where he expressed his heartbreak over finding out that Chyna had moved out of their home, taking Baby Dream and the entire contents of the nursery with her. And since then the two appear to have been battling it out on social media (though both have deleted all of their messages about one another).

Here's a timeline detailing everything we know about the split so far:

Saturday, Dec. 17: Chyna notifies her followers that her Instagram account was hacked, after images of her alleged direct messages (now deleted), were posted. In those messages, she reportedly talked about trademarking the Kardashian name after she married Rob next July, called him things like "fat" and "lazy," and even said she was going to leave him after one year.

Later That Day: Rob Kardashian posted a heartbreaking video about the split on Snapchat, showing fans the empty nursery and discussing how upset he was because it was the week before Christmas and he was now without his fiancee and his daughter. He also revealed she took everything from the room that they'd decorated for her son King, with ex Tyga.

Dec. 17 cont: Rob then posted a message on Instagram, where he wrote: "Sorry to be so open but I'm not feeling so good after seeing @blacchyna messages about me and what her plans were. I have never been this heartbroken in my life. I don't mind being so open or if anyone thinks I'm being weak but I don't play when it comes to family and Chyna was my Family and thought we were getting marries. I treated her as a Queen...I really believed she was in love with me the way that I was with her and I am so hurt and never felt this before. It's different when you have a kid with someone. And after reading Chyna's messaged to her best friend she was going to drop me after a year. She didn't even make it to that. I am so broken. This is a woman I fought my entire family for. I was in love with this woman to the fullest and I was none of that to her."

Dec. 17: Blac Chyna responded with her own since-deleted Instagram post where she claimed to have always tried to help Rob, and claimed he was clinically depressed and refused to do anything about it, writing: "I'M DONE! This entire year I have done nothing but help Rob! It's so SAD & PATHETIC how low he's stoop to cover up his PERSONAL ISSUES! Rob is mentally ill and refuses to seek help! He self medicates which makes ot worse. I have done nothing but help & loved him from the beginning! ...I got him out of Khloe's house, helped him lose all that f-king weight for him to do nothing & gain it all back! Rob asked for all of this! Rob begged me to have Dream! He stressed me out my ENTIRE PREGNANCY!!! Accusing me of cheating, going crazy on me with massive text blast daily! Being an absolute lunatic and then cover it up with gifts! I was verbally abused every other day. I was still there with nothing but high hopes for u!"

Dec. 18: After all of the posts were deleted from Instagram, leading to speculation the two were faking the drama ahead of their special for Dream's birth on E!, airing on Sunday, Kardashian again took to Instagram, with another since-deleted post where he assured fans it was all real.

"People are tagging me in these memes and just cuz I'm posting them doesn't mean this wasn't all serious. This is all very real and serious to me and I'm trying to cheer myself up with these and they are making me laugh. So relax. This wasn't fake or some publicity stunt. Trust me. My one month old beautiful baby girl got taken from me along with my wife who left me. Been upset for days so relax. This is all very real in my life. I don't play when it comes to my woman and my baby."

Also Dec. 18: Kardashian then posted a since-deleted photo of Dream, saying "I really miss this girl...never felt so in love with someone the way I do with you Dream! Look she has her thumbs up. Never thought a woman would try to take my happiness when all I wanted was to make her happy. Man this is awful. Closing my eyes cuz this is draining.

Dec. 18: Chyna and Kardashian then got into it in the comment section of his photo of Dream.

Chyna wrote: "Rob stop it man! I sent u this pic!!!!!

Kardashain replied: "@blacchyna and u texting me on my comment section here proving my point even more. U blocked me and it's f**ked up and I'm heart broken. I loved every inch of you."

As of now, neither one has commented further on the split.
