Dawn, my gut is that this is def not rape. I don't buy for a second the 'i buried it for 14 years' claptrap - she discussed it the morning after. it's horrible and embarassing but it's not rape.
Interesting that she has enquired as to what affect ehr little revelation has had. This is not seeking help, this is attention seeking.
This is a symptom of her breakdown rather than being the cause of it. She has chosed to be a bit of a wastrel with her life and doesn't sound very good at taking responsibility for her actions - this is another evasion of responsibility. She clearly feels bad about this and has someone to pin it on.
You do need to be kind to her, she sounds unwell to me, the fact that she has so freely divulged this to others also is stange, not exactly timely or appropriate.
Be really careful, she sounds like a attention seeking nutter. Interesting that they BOTH give the very same account of the event - he stopped immediately and intent in rape is everything, you don't suddenly find yourself raping someone it is a violent and premeditated attack.
Your poor H - this is a horrible thing to happen to him too as he seems to have done the right thing at the time and now has been very honest with you - he didn't bother to deny it or blame her either which again to me is very telling.
So if two terribly pissed people are making out half asleep and they start fucking and then one wakes up and says no, just because she hasn't said yes out loud before, is that rape????? I don't think so. If you wake up and say no and that person stops, it is not rape it is a drunken mistake. She makes a bloody mockery of real rape victims.
Keep close to your H - I really feel he is the innocent party as you are.
