Not nice subject matter, be warned. Name changed due to sensitive topic. So my little sister (33, anorexic) told me my father abused her when she was around 7. She's not sure how many times (could be twice, could be 20) but she has a vivid memory of it happening twice and in which room at home. Hands down pants basically. I'm shocked. I don't know what to do with this information. She said this memory only came to light in the last year. She's been mentally ill for years. I am one of 6 (she's the youngest) and afaik nobody else has experienced this. Can't say it to my elderly mum. Or my other siblings as we're not close and sister has sworn me to secrecy. Parents are divorced and I don't often see him but not on terrible terms. What do I do with this information? If it's a false memory (she's always in and out of hospitals and therapy) then it's a terrible slur on an innocent man. Never happened to me. If it's true, then what?
