I think I'm on the other site you're on too. One thing I wanted to suggest is that you look into any counseling available at the college where your daughter is going to attend in the fall through their health services office/dept. Is she dorming or commuting? My son disclosed just before he went 3 1/2 hrs away, and fortunately his college offered counseling free of charge to their students (it's an outrageously expensive school, so in a way we were paying for it if he used it or not!).
I'm so sorry for all you are going through. It makes me sick for you and breaks my heart that your daughter was violated and the perp is so arrogant and really doesn't care. I'm glad you're reaching out for support here. (((hugs)))
