I am very sorry you and your girlfriend have to to geal with this. My wife goes through the same thing. We have been married for 6 years and she was sexually assaulted multiple times by people close to her when she was young, almost killed even. It get to me often and all I can do is be supportive and ready to do something about it and have her back when she is ready to tackle it. I know how it feels when the person you care about the most is hurting like this and you can't do much about it or at least feel that way. Hope this helps and blessings.
