The couple have not split up, despite Kardashian's decision to move out of the model's home and into his own Calabasas house, the 28-year-old wrote on Instagram, Sunday.

Alongside the message, Kardashian shared a close-up selfie with Blac Chyna, 27.
A source told PEOPLE earlier in the day that Kardashian and Blac Chyna had fought and needed "some space."
"They have had a great few weeks, but things got too serious too fast," the insider shared. "They were spending a lot of time together and not giving each other enough space."
Blac Chyna had seemingly alluded to a split on Sunday, posting a now-deleted image of a woman reaching out toward the camera with the message, "When you just get out of a relationship & you hoe friend welcomes you back into the World of Hoe."
Kardashian had also cleared his Instagram account of all photos with Blac Chyna.
The source said despite the decision to end their co-habitation, Kardashian is "happy at his new house" and will continue to "focus on losing weight and staying healthy."
