Girl tried to go down on my boyfriend

Hannah

My boyfriend of 2.5 years recently went to a concert with his dad. Which first off they aren’t very close as he calls his dad by his first name. His dad has a step daughter that’s 17. I’ll be honest, she’s a little slut and so are all of her friends. Which her friends and her went to the concert as well. My boyfriend is 23 and I know people probably say this a lot but he’s the most trustworthy person I’ve ever met in my life.

Apparently one of her friends tried to go down on my boyfriend after the concert while he was unconscious and the only reason he knew was because he woke up and she was trying to get him off so he pushed her away and told her to F off. I’ve never wanted to hurt somebody so much in my life. I have met the girl and even if she didn’t remember me personally she knew that he had a girlfriend.

I honestly just want advice as to what to do. It’s been a week since he told me and all I’ve wanted to do is call the cops on her for rape but I’m not a witness and I doubt they would believe a guy that’s 6’3” over a girl that’s like 5’6” and almost 6 years younger than him.

I also had a dream that I killed her and I think that’s the best sleep I’ve had in days..
