The drama in their union began just days before Khloe gave birth to baby True on April 12, 2018, when Tristan was caught on camera making out a series of other women.
Khloe's dismay was caught on camera on an episode of Keeping Up with the Kardashians.
"It is f***ed up. And he’s a complete piece of sh*t," she admitted on the show that aired late in 2018.
However, Khloe allowed Tristan to witness their baby's birth and seemingly forgave him.
As Radar reported, however, Khloe got fed up before Valentine's Day and they split.
In Touch Weekly then reported that Tristan and Jordyn partied together at ShoreBar in Santa Monica, Calif. on Sunday, February 17, 2019.
Then, Tristan and “about eight girls” — including Jordyn — followed him back to his home in Sherman Oaks for a house party. It was the last humiliating straw for Khloe.

The news broke on April 10, 2018, when the 27-year-old NBA star was caught on camera making out with a mystery brunette at a rooftop bar in New York.
In other videos posted online, Thompson can be seen clearly making out with the sexy woman, while another woman joins the party and seemingly rubs his face in her breasts.
The duo’s romp didn’t end there. The mystery lady was again spotted leaving Thompson’s hotel the following day wearing the same outfit as the night before.
The mystery woman was soon revealed to be Instagram model Lani Blair.
A very pregnant and heartbroken Khloe began shutting everyone out as she dealt with the betrayal.
“She is trying to pretend this isn’t happening and keeps saying that she must put the health of her unborn baby girl before these lies,” a family insider told Radar at the time. “When she spoke to her sisters earlier today, she assured them that this was all a big misunderstanding and that Tristan would be able to explain it.”
On April 12, Khloe gave birth to a baby girl.
Just moments after giving birth, Khloe and Tristan had a fiery showdown inside the delivery room.
“When the baby was delivered, and the nurse took her away from the delivery room, Khloe just snapped at him,” a source told Radar exclusively at the time.
A few days later, it seemed Khloe and Tristan had made peace, as the new mom shared a photo of her daughter on Instagram, and captioned it, “Such a blessing to welcome this angel into the family! Mommy and Daddy loooooove you True!”
The troubled couple entered couples’ therapy in an effort to work things out.
“(Tristan) is incredibly remorseful for everything that has happened and doesn’t want to cause Khloe any more pain,” a source told Radar.
The two tried to make things work for the sake of their daughter.
With Radar reporting that Khloe split from Tristan before Valentine's Day 2019, the baby daddy is now embroiled in a cheating scandal involving Khloe's sister Kylie's friend Jordyn Woods. According to In Touch, she went to the NBA star's home where they cuddled on a couch on February 17, 2019.
“Tristan and Jordyn were into each other, they were cuddling, holding hands,” a source told In Touch. “Tristan was rubbing her a**, they were definitely hooking up.”
Incredibly, Khloe had exchanged social media words of affirmation with Jordyn on the same day she hooked up with the KUWTK star's baby daddy.
According to Us Weekly, furious Khloe confronted Tristan about the allegations that he hooked up with Kylie's best friend at a house party on Feb. 17.
A source told Us Weekly, "Khloe was told by people who saw Tristan and Jordan making out. Khloe confronted Tristan and he admitted it was true." Now the two are history!
