The 29-year-old reality star said in an Instagram post Monday that he's "seeking help to deal with [his] flaws/issues" after publicly announcing that Blac Chyna had left him and taken 1-month-old Dream.
"This weekend I was in an emotional bad place and did some things that embarrassed myself and my family. I apologize and I'm seeking help to deal with my flaws/issues. Please pray for me and I'm sorry @blacchyna. You are a great mother to our child and I love you," Kardashian wrote.
"I am going to get better for you Dream. You are my life and gave me a new start on being a better me. Love you," he added to a photo of his daughter.
Kardashian had shared a series of emotional posts Saturday after Blac Chyna's Instagram account was reportedly hacked. Screenshots of alleged text conversations appeared on her page, including one where she declared, "Imma give Rob 1 year to get it together. Or I'm gone."
"My one month old beautiful baby girl got taken from me along with my wife who left me," Kardashian said in a since-deleted post. "Been upset for days."
Blac Chyna later claimed in a since-deleted post that she left Kardashian because of his "personal issues." The 28-year-old model confirmed she's "done with the situation" until the reality star "gets help."
"I'M DONE ! This entire year I have done nothing but help Rob! It's so SAD & PATHETIC how low he's stoop to cover up HIS PERSONAL ISSUES! Rob is mentally ill & refuses to seek help! He self medicates which makes it worse" she wrote.
Blac Chyna responded to Kardashian's apology by re-gramming his post and captioning it with a heart emoji. She and the reality star got engaged in April after three months of dating, and welcomed Dream in November.
