Did the Husband of Petraeus' Mistress Write NYT's 'Dear Abby'?

Coincidence? It sure fits the details. Check out this letter written in July to the NYT's The Ethicist column:

My wife is having an affair with a government executive. His role is to manage a project whose progress is seen worldwide as a demonstration of American leadership. (This might seem hyperbolic, but it is not an exaggeration.) I have met with him on several occasions, and he has been gracious. (I doubt if he is aware of my knowledge.) I have watched the affair intensify over the last year, and I have also benefited from his generosity. He is engaged in work that I am passionate about and is absolutely the right person for the job. I strongly feel that exposing the affair will create a major distraction that would adversely impact the success of an important effort. My issue: Should I acknowledge this affair and finally force closure? Should I suffer in silence for the next year or two for a project I feel must succeed? Should I be “true to my heart” and walk away from the entire miserable situation and put the episode behind me?
NAME WITHHELD

UPDATE:

NYT's Hugo Lindgren is reporting that the above letter is NOT from Broadwell's husband. Which means there is still another high level cheater in the government,
