About 8 years ago i was raped by someone who lived in the same student house as me. I never reported it, i told my mum but she blamed me cos id been drinking that night, plus others said the same, who i turned to. It's recently happened, not as in he raped me, but he tried to. he attempted to. And i had a hard time with this recently. I joined an Aspergers Awareness group of which we have monthly drop-ins. This is where i met the said guy who tried it on. He has aspergers so i'm aware maybe i was giving off confusing signals. but that time he tried it on really frightened me and set alarm bells in my head. i had a massive panic attack. Now i'm not sure if i want to go to the drop-ins anymore in fear that it will bring up bad memories again.
Whether you are drunk or not, when someone forces you to have sex without your approval, it is rape. It is unfortunate that your friends and, importantly, your mother blamed you. They were wrong. You need not to blame yourself for that moment in time 8 years ago.
Is it necessary for you to go to this asperger’ awareness group? If so, you need to talk to the person who is running this group and let him/her be aware of this man who is making unwanted advance on you.
Finally, I get the feeling you are a friendly and gregarious person. Some people may misread this as an interest in them. Don’t fret over this. Take charge of you life. You can do this and get rid if your anxiety. I can say this because I been down the same road.
