No. The "claim" of an EX- boyfriend should be taken as just that: a "claim" (not a fact) and form an "ex", who most likely has an ax to grind. Let him bring outside proof of this fact relying on something else than just his own testimony about that. No court, and court of public opinion, should otherwise condemn on such a flimsy basis.
Secondly, I did not comment one way or the other on her qualification for the job. That's why I specifically said it was a separate question, which I was not raising.
My basic point is that I think she was so attacked because she was the woman in the relationship and that a man would not have been affected by such accusations in a similar way. And I think it stinks either way, but even more so because we still seem to ask, somehow, for women to have a "higher" moral or personal virtue level than the one expected from men.
