@Miss_Basilisk I'm so sorry you're even having to ask this question. It's a traumatic experience.
I did go and file a police report. At the time I think I was still in shock that the whole thing had even happened. My husband really wanted me to go through with it - if for no other reason, then maybe get this guy off the streets.
Filing the initial report was very hard. We didn't need an appointment. We just went in. My husband did the initial talking...told them I needed to file a report. My husband stayed with me and even added to or helped me to verbalize it when I got chocked up.
Once the report was filed, he said it would be handed over to a detective specializing in sexually based crimes. He gave me a couple of hotlines I could call anytime as well as a rape crisis Centre. Personally, I didn't feel any better about it after filing the report. No closure or anything.
I got a call from a woman detective a couple of months later. I was given the choice as to whether I wanted to pursue it or not.
I chose to go ahead with it. I was assured it would all be confidential and only with women. No men would be present. I could have my support person with me at the station, but not during the interview.
I first met with two detectives, not recorded. Introduced ourselves, they shared about themselves...regular chat.
Then I went alone with the woman who had initially called me, into a room alone with a camera and a recording device under the table where we spoke.
She was very open and receptive to everything. Told me where everything was and why it was there. Answered any questions I might have. Once I was ready, she started a formal interview.
I ended up drawing a diagram of everything. It helped me to talk about it. Honestly, it was a very painful experience that I don't ever want to repeat. It's very hard to talk about and share your trauma, but as I was assured, even if nothing comes of it, I've given them information about this person that is now in the permanent records. They had an official report and an IMO.
The experience itself was all very positive. They made every effort to make me feel as safe and protected as possible.
I don't know how things work in your country. What the procedures are, forms to fill out. I can only hope that you might have a similar experience as I did.
But I really am sorry for whatever you've gone through. I hope whatever you choose to do, it'll be your choice alone and for your own reasons.
