He just says he has no idea why he went along with it. Can't really remember that much and was just trying to fit in.
He can't rememebr that much, but yet filled you in on who she was and the fact she helped him 'carry a mate' back to his cabin. Managed a quick selfie inbetween. But Can't remember that much. Amnesia is a cheaters first port of call. Sorry OP.
And then he said yes, but a rumour did start about him. And then I was like and what you went along with it? And then I just laid into him about how disrespectful it was. And since then I've just had vague bits and pieces from him.
Amnesia is often followed swiftly by vagueness. The vaguer the better. So they can turn it into you feeling like you're interrogating then because, well, thats how it ends up, as they cant give an answer that isn't, well, vague. Amnesia is still well and truly in the picture here by the way, but obviously complete amnesia isnt working so a few vague answers should hopefully shut you up.
Noone else has brought it to my attention. Other than the stag who said he was sorry for not shutting it down when it came up straight away.
Yet he thought it best to tel you about the 'rumor'. That would be the damage control stage OP. That is slightly before the amnesia and the vagueness stages.
Apparently she and him took one of the other drunk stag party back to his cabin. She helped him apparently.
Perfect. That would be the cover for them being seen leaving together and being in his cabin together. Because obviously you'd choose a girl you'd only just met to transport a heavy drunk bloke, that she doesn't know, to his cabin. Asking any of the blokes there on the trip with you would be ludicrous! And obviously young women all over the world would help a random stranger (one who can't remember much because he was also drunk? Assuming it isn't cheaters amnesia of course - benefit of the doubt and all that), carry a drunk bloke to his cabin. I mean, what girl wouldn't absolutely step in and immediately help this poor man, who didn't have snyone else there to assist with said drunk friend.
Oh wait.....
I've also been told that noone saw anything inappropriate.
Well no, I assume they weren't getting it on on the viewing deck. Cabins tend to have doors.
And yet, there is a rumor. How strange such a rumor started when absolutek nothing inappropriate was seen.
OP, I'm sorry. He is never going to admit to anything because nothing can be proven. It was a rumor after all. At least he can remember that part, hey. Thank goodness that isn't terminal.
My advice, Get an STI test. In fact, even better - ask him to get one and see how enthusiastically he accepts that request. My guess is he'll fleetingly look a bit like a deer caught in the headlights, agree to it and then continuously 'forget' to book the appointment. God damn that amnesia!
And ask him the girls name. if he says he can't remember - hes lying.
They chatted alot, they had a picture together, she helped him carry his mate (apparantly). They were on a cruise and all partying together. He would have got her name. If he says he can't remember her name, that she was just 'some random girl', well, i'm sorry, but thats a huge giveaway.
