@Megano! Okay, I created an account to make this comment - please don't ever tell anyone that they should change their mind about pressing charges. A victim does not owe anything to the world at large - the rapist owes it to the world not to commit crimes.
Besides, let's be real - less than 10% of cases are even brought to the stage of a trial, fewer are convicted, and even fewer serve prison time. I was a rape crisis counselor for three years - not a single person who I served had their attacker convicted, and only a few were even brought to the prosecution point. I say that not to discourage anyone who does want to go through that process, but to put it in perspective. If you don't think going through that process is going to be helpful to you personally, don't feel guilty about it, because chances are, nothing will happen to your rapist anyway. This is unfortunate, but it is the truth, and survivors deserve the truth.
