I have to agree with Carl. In criminal law, since both parties were of equal age and there doesn't appear to be any threat or use of force, I'm not seeing any prosecutor moving on a criminal case, unless it were to be against both parties (which happens SO rarely). In other words, the criminal elements that could constitute "making" her participate don't appear to be present. Emotional pressure alone, among otherwise consenting minors of equal age, just doesn't tend to reach the level where a prosecutor could make a criminal charge stick. With that said, there is nothing to prevent her from making a police report - however, it's vital that she understands that doing so means that were any criminal prosecution to commence, that she'd be faced with being called to take the stand, and describ in lurid detail the events that occurred. This isn't something to be taken lightly, especially in light of the problems she's already experiencing - and, is something that she should consider only after consultation and hopefully thorough work with a qualified therapist. The process of moving a sexually-based crime through the court system is often MORE traumatic than the events themselves, and when a person is already having major daily aspects of their lives disrupted, adding the additional pressures, stresses, and exposures of the criminal process can push emotional limits to the extreme and beyond.

PLEASE so not under-estimate the need for counseling. Minors who are or who perceive themselves to be victims of sexually-based crimes are 30% more likely than non-victims to develop PTSD and similar conditions, as well as almost 10 times more likely to make a suicide attempt. Getting professional help is SO important, it cannot be stressed enough - and the sooner, the better.
