Rob Kardashian and Blac Chyna fought over "ridiculous" things.
The ‘Keeping Up With The Kardashians’ star was left "heartbroken" after the 28-year-old model walked out with their one-month-old daughter Dream.
A source said: "He has absolutely been the instigator in most of their past fights. His emotional problems takes over and he lashes out at Chyna over ridiculous stuff. Chyna just had a baby and he keeps fighting with her over ridiculous things. It’s like he just can’t help himself.
"Whenever he gets along with Chyna, he finds a way to ruin it. He is crazy suspicious and doesn’t trust her at all … Now he keeps fighting with her over issues that his family had from the beginning. He doesn’t trust that she actually loves him and that their relationship is only about money to her."
And things are reportedly a "crazy mess" between Chyna and the 29-year-old sock designer at the moment.
An insider added to People magazine: "But it just seems it’s kind of too late to have these issues now. Rob is a dad and that should be his focus.
"He cries now that he misses his baby, but he isn’t mature enough to not start fights with Chyna in the first place. It’s just a crazy mess. A very sad crazy mess. It’s just sad that he treats the mother of his child like this. Rob and Chyna are like oil and water. They just bicker constantly. It’s not healthy."
Earlier on Sunday (12.18.16), Rob took to social media to admit he really "misses" his daughter.
Sharing a collage of pictures of the little one, he captioned it: "Pretty Dream … miss u pretty mama (sic)"
He also shared pictures of the empty rooms on Snapchat.
