Below the now-deleted photo of the infant, Rob emotionally captioned, "I really miss this girl. Never felt so in love with someone the way I do with you Dream! Look she has her thumbs up."

"Never thought a woman would try to take my happiness when all I wanted was to make her happy," he continued. "Man this is awful. Closing my eyes [because] this is draining.”

His heartbreaking confession comes days after Chyna's Instagram was hacked, exposing the model's intent to use Rob for money and increased fame. There is no word on whether the couple has reconciled, but the reality star recently apologized to his former fiancée in addition to admitting he's seeking help.
