If you want to write off "the one" because she hooked up with your buddy, but you can't knock someone else for wanting to overlook something that isn't wrong. For the record, men to the same god damn thing. "I didn't ask her to be exclusive so TECHNICALLY I'm still single...." yeah whatever. Don't blame women this can be done by both sexes.
So you believe lying by omission is still lying- whatever. I don't she didn't lie, he never asked... (unless he did ask and she did lie... don't know). I would NEVER tell a potential man "oh yeah, I blew your buddy so and so..." Sure, I can understand if he's upset when/ if he finds out... I would even understand if he dumps me. But I know that's none of his god damn business. Nor am I "lying" about it by not telling.
