Therapy and decision to report violation, or not?

OK, so I went to therapy today, and told the therapist about the phone call my girlfriend got from my husband. I also told her how he tried to get a phone number out of my friend, by trying to trip her up. This is a clear violation of the protection order. My dilemma lies herein. My friend is afraid of him. She also has a lot of stuff going on in her life. She is in foreclosure on her home.
The last violation I reported, a call made to a friend, angered her husband so much, that he is as mad as a hatter with me. Simply put, he does not want to get involved.
It's a strange thing to try keep yourself safe. Reporting a violation. The abusers pick your friends who they know are weak. Thus the cycle of abuse continues. These men/ women know how to pick off your friends as well.
It's very frustrating to say the least. Makes me want to shout and scream.
