First off, thank you for this site. It's wonderful. Now, I'm a just-graduated senior, and my best friend went with a big group to Florida for their senior trip. She called me wasted and crying, upset and saying that this guy I'll call E wanted to have sex with her, she told him no, and he did it anyway. His side of the story was that she didn't protest. Sounds like rape, right? But she's known for teasing guys, and people might not believe her. And they liked each other a while back--E never displayed any signs of being likely to take advantage of someone.
I have no idea how to handle this situation because there's so much gray area. How can I help my best friend?
