My girlfriend is 14. She got molested by her brother. I have no idea what to do. I'm the only person she has told

First off what state or country is this happening in?

What form was it? Groping or something further?

How old is the brother?

USA, west coast. He moslested her when she was around 6-8 from what she can remember. It was just touching the vagina. He would do it while she was sleeping. Also he is around ten years older. She is starting to remember more and more.

She needs to seek professional help. They may or may not be repressed memories.

Sexual assalt is not something that most people can deal with alone it may hurt your relation ship now but if she won't say something you need to. Abuse leaves more than what people see or hear about. What you have heard is just what she can remember she needs help before it causes more problems. A true friend is not afraid to lose the others friend ship. It is more important to keep them safe than to keep quiet
