The West Wing

[JHyde]

I really thought her loneliness was one of her weaknesses, and probably caught her in it in the first place.

As to why she blamed herself, I think it was more because of what it was than how it could be used against her, although that was certainly a factor. Remember that she did not hesitate to threaten him with her coming out with any other women he might malign once the press got hold of them. She was serious in that threat.
