I just got home from travelling and saw this thread. Cris, please know that you, your daughter and your entire family are in my thoughts and prayers.
As a survivor of abuse, though not to the extent as your poor daughter, let me say that your love and support will be as needed down the road as it is now. Keep telling her how brave she is and how much you unconditionally love her. Always reassure her that NOTHING she may have done rationalizes or excuses this behavior!
This is probably not the first time he abused her and he probably has/had her convinced that somehow she brought it upon herself. The embarassment of others finding out what she has been tolerating can be overwhelming as well. Feel free to get my email from Jack in the future if she feels she would like to communicate from someone who has been there and made it out.
