So a couple years ago I was at rock bottom. Borderline homeless; horrible alcoholic. I was scarred by a physically abusive relationship I had finally managed to leave.
The place I was staying at wasn't much better. Everyone was on drugs.
One night I got into a fight with one of them, and I needed somewhere to sleep.
I called my ex; we had been broken up for about 7 months at this point. Sometimes he'd give me a ride somewhere, and we still talked occasionally. I asked if I could crash on the couch. He said yes.
I got piss drunk that night, and fell asleep alone in the living room. When I woke up his fingers were inside of me. I pretended to be asleep.
This very same thing happened again about 3 months later, but this time I confronted him when I woke up to it. He got upset. He told me to just stop talking about it.
Now that I have been sober for a couple months and out of touch with him for over a year those memories have come flooding back. I feel completely violated, and I've had a couple nightmares about it.
Does this qualify as sexual abuse? What's your opinion?
For the record I'm not looking to shame him or anything like that. I don't want to talk to him, and I don't want anyone in my life to know about this.
