The reality star took to Instagram on Sunday to post a new photo of his 1-month-old baby girl, Dream, along with a message about how much he misses her after his fiancée, Blac Chyna, took their daughter and left the house on Saturday.
"I really miss this girl," Kardashian wrote in the since-deleted post. "Never felt so in love with someone the way I do with you Dream! Look she had 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."
Chyna, who recently deleted a number of Instagram posts regarding her fight with her fiancé, also appears to have started a new, secondary Instagram account. Chyna posted a Snapchat video to the account -- which is unverified and was later made private -- to prove it was really her posting content.
On Saturday, Chyna cleaned out Dream's nursery, her son King Cairo's room and the pantry at the house she shared with Kardashian. She later took to Instagram to announce that she's "done" with trying to make their relationship work.
"Everyone has tried to help Rob. I've gone beyond to help and so has his family! I'm done with the situation until he gets help. I have no longer have time to feed into Robert's shenanigans I have 2 children and myself to fend for," she wrote.
Chyna's mom, Tokyo Toni, took to Instagram on Sunday to assure people that the couple "will be fine," despite their problems, and that she hopes they can find their way.
"I love Rob and I am going to try to help them manage their relationship through love and wise words," she wrote. "At the end of the day they will still be together I promise you. Rob just have to get Mr. Insecure off of his back! Everything will be fine."
