I just get really hyper when I'm drunk but I always want to tell people intimate details about myself anyway so I'm not much of a judge. A friend of mine does tell the truth though, apart from being completely dazed at one point saying "I can control time!" (He's a Brummie, it makes it all the more hilarious), he asked me "Do you think I need a girlfriend?" and I could tell beforehand this is something that had been bothering him but he just didn't have the courage to talk to me about it, so there you go.
As for you're friend, I imagine pride has a pretty high part in it for her, she doesn't want to loose face and admitting she wants you as a mate again to you would mean you had the upper hand. I reckon if you get her on her own and talk to her seriously, eventually she'll come around one way or the other, then at least it will be sorted out.
