My friend was gettin abused by her bf so I told her parents and they called the cops ?

When she found out that I was the one that told them she was angry and said she never wanted to speak to me again. I had to tell them he was hurtin her really bad and she didn't want to say anythin. I tried tellin her I'm sorry but she still wouldn't talk to me. It's been like 4 weeks already. I knew her since I was 4. I was jus tryin to do the right thing and she's like pissed at me. What should I do? Was it wrong that i told them or something? If she died it would have been my fault because I knew what was happenin to her and I didn't say nothin.
