I'm going to report a sexual assault that happened to me months ago even though I carried on a friendship with said abuser
Why did you continue to be friends with your abuser?
It has been too long since it happened.
There is no limitation on when a victim can report abuse to authorities. You should also talk to someone about your pain and see how you can move on from it.
Do you feel sorry for me?
Yes, I am concerned about your mental state. It would be wise to seek out professional care after you have reported this incident. You should try to eliminate the toxic people in your life and surround yourself with people who care about you.
