I found out by accident today. She's 22 and lives at home. She'd used my laptop and left her emails logged in, when I went to close the page there was his name at the top of the page. I had a panic attack just seeing it. He was extremely violent, including while I was pregnant, and left when she was a baby. With the support of my family I threw him out. There followed a terrifying period during which time he repeatedly threatened to abduct her and kill me. He tried to once but the police arrived. Many other incidents and a panic button installed by police. They never charged him. We moved away and he gave up. The relevance being, I have virtually no proof. Do I tell her what he did? I read the emails - he blamed me for splitting up the family and she agreed. Would she even believe me? I'm in shock and so confused.
