This happened a long time ago, about 20 years ago. They'd been in a relationship about 4 years. We we're in a club and he trapped me in a corridor near the toilets and sexually assaulted me. I don't know what would have happened if someone hadn't heard me shout stop and come around to check if everything was ok.
At the time my sister was an alcoholic and very mentally fragile. I worried about her a lot. I was very young and I didn't know what to do. But rightly or wrongly, I never told her or anyone else what happened that night. Thankfully they split up shortly afterwards and he ended up doing a stint in prison when they lost touch.
Now 20 years on and they've become friends again. My sister has been dry about 8 years and is married with kids and a much more together person. She keeps saying how great he is, that she's so glad their friends again. I really don't think she'd cheat on her husband she's not the type and she's loves him a lot. But she's is getting closer and closer to this awful man and it kills me when she tells me what a wonderful person he is.
Should I tell her? If I do I know she will be devastated that I never told her, I think she'd fall apart too. She's very protective of me. If I don't, then I'm hiding something really important from her. But it happened so long ago, maybe I should just let it go.
I just don't know what to do.
