Intense anger is totally normal and has it's purpose. It can be protective and motivating to follow through. Everything in your last post is justified. Your anger at him, at the police, at the system that allows this to happen. This is the major reason why women don't feel safe enough to leave but it can be done. Hundreds of women every day go through this. Go meet some. Many DV centers do group counseling. Someone recommended the book "Why Does He Do That?". It's excellent. Now that they brought it up, I'm going to pull out my own copy and reread it. Really it's an excellent resource for answering all those unanswered questions you must have. Take care.
