Sad thing though, she knows alot. I would be very careful if I was her. We know what wedding vows can do to you. She would have more rights if she stayed living with him.
And a lot of very stupid women take up with men with abusive histories. (Even serial killers of women get love letters!) The women , if asked if they aren't concerned about their men's pasts, usually explain smugly that the other women in his life weren't "woman enough" , "sexy enough", or were otherwise to blame for the abuse, because of their (the other women's ) deficiencies. It could never happen to THEM-they're too 'special', too sexy, too beautiful etc etc .
