As I said in my first post, I don't believe that she was leading him on at all. She was very clear that she wouldn't sleep with him because he was married.
But it has to be pointed out that he was her boss for the first 5 months that they knew each other. That's how they met. She didn't work for him after those 5 months, but he could still have been helpful to her career advancement. (Article since removed, that's what I read the day the story broke).
For me, no amount of career advancement would be worth putting up with someone who doesn't understand "NO. Just FUCK OFF and stop pestering me" for 2.5 years. I think most women would feel that way. So I wonder why she maintained contact with him. I'm not implying anything; I'm wondering. It's likely, to my mind, that in those 2.5years he probably did do something to help her professionally. That would explain why he "persisted" with someone who told him no for 2.5 years, and she put up with someone who leched at her for 2.5 years. That doesn't mean there is some quid pro quo, before anyone shouts me out (other than, perhaps, a career-based favor in return, irrespective of seniority). So, I think it's likely, that he has been of use to her at some point in those 3 years. And so, it is what it is. The "bargain" is that he tries it on, she rejects him, he probably helps her out here and there and in return she puts up with his lecherous ways while keeping him at arm's length. Somehow it came to a head, for whatever reason, and she outed him.
It's a fine line to tread. His behavior was undeniably gross, ugly - just ugh. Whatever his behavior, though, why didn't she just walk away the first time she had to tell him to fuck off? She owed him nothing after 5 months.
