I am so sorry this happened. This was definitely not your fault. I would never in a million years use the words 'dumb slut' to refer to your behaviour (I don't think I'd use the phrase ever, but that's another story). You explicitly stated what you wanted and you were ignored. I also understand your desire not to get him in trouble and 'create drama', we're often taught as women that we should not cause a fuss or create drama for other people. That's not true. If you want to do something more about this, you can. If you don't, you don't. There's no right way.

I just wanted you to know that you are not in the wrong, what happened to you is not your fault and I'm sorry.
