Their break-up is becoming very messy, with both Rob Kardashian and Blac Chyna filing lawsuits against each other.
But with her recent case against Rob and the entire Kardashian-Jenner family, things are also becoming very public too.
In court documents obtained by News.com.au - which include allegations of assault, battery, domestic violence, defamation and interference with prospective earnings - some of Rob Kardashian's text messages to the mum-of-two have been revealed.
And we have to say, they're certainly a rollercoaster.
According to the papers, Rob says he's suicidal over text on multiple occasions.
In one screenshot, Blac's ex says he wants to overdose because she didn't share a photo of a Ferrari he'd given her on social media.
“Sh*t is wack as f**k,” Rob wrote. “To the point where you got me taking pills.”
“I’m literally on the verge of killing myself and u couldn’t care less,” he wrote on another occasion.
Just like the break-up, their relationship was just as turbulent.
The pair got engaged after 10 weeks together and had their daughter Dream in the same year.
But in July, Rob attacked the mother of his daughter on social media when he posted several naked pictures of her, claiming he was doing it because she slept with another man in 'the same bed Chyna and I made our baby in.'
Rob filed his own case against Blac Chyna last month that alleged his former fiancée threatened him with a gun while on FaceTime and also tried to strangle him with an iPhone cable whilst staying at sister Kylie's house.
As well as the private lawsuits, Rob could face revenge porn charges.
