Kenya Moore complained that Porsha Williams has never apologized for physically attacking her, during last year's Real Housewives of Atlanta reunion special.
The "Gone With The Wind Fabulous" singer, in her new Bravo blog , said she was disappointed that her castmate could not come to admit she was wrong in the 2014 outburst -- that was caught on Bravo's cameras, and wound up getting her arrested -- during a recent cast therapy session.
"She has never once apologized to me for physically attacking me or any other verbal offense over the years," the former Miss USA wrote of Kordell Stewart's ex-wife.
Moore wrote that the lack of any remorse on the part of her reality rival proves that Williams "is simply incapable of moving forward" from the past drama.
Moore stressed that "you can't keep pointing the blame at someone else, and never take any responsibility for your own actions," admitting that she herself has changed for the better as result of deep soul searching.
"I did months ago, and my life changed for the better," Moore wrote, adding that on the whole, she believes the therapy was a positive thing for the bickering cast.
"I definitely feel some progress was made," she wrote. "Change doesn't occur overnight, but I believe if you are willing to listen, that leads to an understanding.
"From there, you can only try if your desire is to move forward."
The Real Housewives of Atlanta airs Sundays at 8/7c on Bravo.
