Really appreciate the nice words Cavemum, cowgirls, Inigo, thank you.
Not at all brave, sadly, as can only (and will only) ever talk about it in anonymous way on here.
Also, while if I heard about that exact thing happening to someone else, I'd say too, like you cowgirls, it sounded an 'awful ordeal' it's impossible to connect those words to the experience I actually had. As I say, the whole fact I got dressed up in sexy mini-dress and heels and went to the party wanting to flirt, snog etc, and then got drunk, and then found myself in the position of going up the stairs without - I don't know - refusing or something... knowing, logically, that none of those things mean he should have done what he did, and that I'd be murderous if anyone did the same to my DD or a close friend, I still can't quite connect the fact that it was so wrong.
Again, I can totally see why so many women stay silent as it is hard, almost impossible maybe, to totally truly believe you weren't partially responsible.
