"If you cheat once, don't tell," the 42-year-old mom says in her new book, "Life Is Not a Reality Show: Keeping It Real With The Housewife Who Does It All." "You get a free pass."

When asked about her stance on cheating during an appearance on "Good Morning America," Richards said she knew "I was going to get some heat for that."

"I've seen circumstances with people that I know are in love with their spouse and they made one mistake, and I said -- this is somebody that I know, nobody that anybody knows here -- 'Listen, if this really was a one-time mistake, and you did not put this person in jeopardy,' I personally think you should deal with it with yourself and with God and not go and say, 'Honey, look what I did,' because I knew that this would ruin their relationship and their life," she said.

"And I can tell you that many, many, many years later they're happy and together, and she did make that mistake and she has to carry that and live with that," Richards added.
