"For a long time I felt like King was going to be an only child. That he was my greatest blessing and we were gonna live happily ever after together Just the 2 of us," Chyna wrote, referring to her 3-year-old son, King Cairo, whom she shares with ex-fiance Tyga. "I was no longer looking for love because I thought I had all that I needed. We needed."
