After hearing her mother's reunion comments about their relationship strain, Sidney Barney accused her mother of being abusive, and of using her for a story line on The Real Housewives of Orange County.

"I watched the reunion show last night and I am disappointed," Sidney wrote. "I try not to talk about personal family matters with my friends, but I was made aware that my mother was talking about me and discussing our personal family matters on the show again."

"The reason I do not live with my mother is not because of my dad, it is because she is mentally/verbally abusive and not a mother to me," Sidney alleged. "For the past two years I’ve been asking her to stop treating me badly, to stop doing embarrassing and talking about me on the show, and to not use my siblings and I as storylines. Clearly she hasn’t followed through with anything that would have made me go back to her house."

"If she really wanted me back in her life she would have taken responsibility and changed two years ago when I told the first time what was causing our relationship to suffer," she added. "Obviously, I am just another storyline that feeds her fame and her wallet."
