Before begin, I know this is probably in the wrong category but I wanted to post anonymously which I somehow couldn't do in General Discussion.
At the weekend, there was a party which a large chunk of my year group went to, but I didn't. Whilst there, my ex-boyfriend met a very drunk girl (as in drunk to the point of not having a clue what was going on). He ended up touching down south, and taking photos and videos of him doing so on his phone. I don't know if the girl was aware what was going on, but even if she was I'm guessing drunkness would sway the decision she would normally take.
He's now showing these videos and photos to people and seems proud of what he's done. I don't know the girl in question, nor do I know how I could ever contact her. Should I tell someone, such as a teacher? I know it's not my place to say, and it's not really anyones except the girl's (I don't even know her name) but surely it's the right thing to do? I don't think it's right for him to get away with it.
What would you do?
