Why oh why, can't some women own their own shit?
You flirted with him, you gave him your personal mobile number, you sexted him...and now, because he hasn't shagged you yet, you're going to try to get him in to trouble at work, by reporting him?
You sound unhinged to me. You're a grown woman, and you did exactly what you wanted to do. Just because you're a woman, doesn't mean you now get to cry coercion, when this flirtation hasn't gone the way you want.
And I don't believe that you thought he was separated. At best, you say it was a rumour. Didn't you think to check this out, before swapping sordid messages with a married man?
You sexted with a married man, and it didn't end well. Quelle Surprise. Grow up would be my advice.
I sound a bit harsh, I know, but I'm so fed up of women behaving badly, and then when it goes tits up, they use the old "I'm only a woman, and he made me do it" excuse.
