Just to say that you have done the right thing for you in telling the police.
Even if nothing comes out of this, you have done what you could to punish this man for his actions and have taken control of the situation. Which it was what he took from you through his actions.
Also, reinforcing what izzy said about writing an account of what happened.
It has already helped that you have written it down here, but you should take notes for yourself, including things that you haven't said here.
From a parallel experience, the more we think about it, the more we remember and things that may not make much sense initially then eventually do.
So, even if you don't want to remember it, do try to review the events in your mind.
And remember that it wasn't your doing. It was all him.
