At some point, the full story of Anthony Weiner and his sexual relationships and texting habits will finally be told. In the meantime, the serially evasive Mr. Weiner should take his marital troubles and personal compulsions out of the public eye, away from cameras, off the Web and out of the race for mayor of New York City.

Mr. Weiner, who resigned from Congress two years ago after sending lewd messages and photos of his crotch to women he had not met, was forced to revisit the issue on Tuesday, and so were we all. A Web site called The Dirty had another woman’s story, another round of sex texts, and another picture of Mr. Weiner’s penis. The startling news was that this new episode apparently took place last summer, only a few months before Mr. Weiner was to begin another run at public office. The marital trauma that Mr. Weiner and his wife, Huma Abedin, had said was behind them was not as far behind as we thought.

When the first texts were revealed two years ago, Mr. Weiner lied about it, saying he had been the victim of hackers. Then he owned up, tearfully abandoned his office and retreated into private life. Then he was back, telling the world that therapy and his wife’s forgiveness had turned him around and that he was ready to begin a new chapter. That turned out to be the mayor’s race, which he entered in May. What he did not say then, and what voters did not realize until Tuesday, was that his resignation had not been the end of his sexual misconduct.

The timing here matters, as it would for any politician who violates the public’s trust and then asks to have it back. Things are different now, he insists. “This behavior is behind me,” he said again on Tuesday. He suggested that people should have known that his sexting was an unresolved problem well into 2012.
